The ability to provide a solution with high sealing integrity and low fugitive emissions follows the industry trend for developing a more environmentally friendly solution. There are some existing standards and methodologies that provide a basis for practical testing activities. Other methodologies, such as FEA and hand calculations, are available to evaluate the seal tightness on a theoretical basis during the design stage and predict fugitive emissions values. Test measurement for fugitive emissions is subject to the design of the flange and seal components, the quality of those components, and the test set-up methods employed. This paper will focus on the comparison of different flange designs currently available in the market, as well as a comparison of various metal to metal seal types. The scope of this paper covers flanges designed to ASME B16.5, API 6A, non-standard flanges (e.g. compact flanges) as well as clamp connectors. For metal seals, this paper will cover HX, BX and Techlok seal rings. Test methodologies and set up will be detailed and the test results listed, with the theoretical predicted fugitive emissions values also provided for comparison. Results for previous compact flange analysis are also included for reference.","PeriodicalId":124387,"journal":{"name":"Volume 3: Fluid-Structure Interaction; High Pressure Technology","volume":"182 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121102030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One method for extending the life of hydrogen vessels is recertification through non-destructive evaluation (NDE); however, NDE techniques are frequently evaluated with machined defects in test samples rather than fatigue cracks which occur during pressure cycling and may be more difficult to detect. In this paper, 50 mm wide ring sections (called C-rings, since they represent slightly more than half the circumference) were extracted from pressure vessels and mechanically cycled to establish fatigue cracks. Sub-millimeter starter notches were machined, via plunge electrical discharge machining (EDM), to control the location of crack initiation. Crack growth was monitored via direct current potential difference (DCPD) and backface strain gauges, both of which were shown to be good indicators for crack propagation. The C-ring geometry and fatigue crack growth were modeled to demonstrate the ability to monitor/control the crack length and area, which can be used to develop calibration samples of varying crack depth for NDE techniques. Additionally, this sample is intended to evaluate the influence of residual stresses on the sensitivity of NDE techniques, such as the design stresses in autofrettaged vessels.","PeriodicalId":124387,"journal":{"name":"Volume 3: Fluid-Structure Interaction; High Pressure Technology","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122619868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hydraulic fracturing physical simulation experiments of shallow bright-type coal seams in Hancheng block were conducted. Based on the experiment results, fluid-solid interaction theory, and discrete fracture network model, a 3D fracture network model of bright-type coal seams was developed. Fracture network propagation behaviors under different rock mechanical properties and fracturing operation parameters were investigated. Sensitivity analysis of the influencing factors of fracture network propagation was performed with the grey correlation method. The results show that a complex fracture network dominated by the main fracture is formed after hydraulic fracturing in bright-type coal seams. Fracturing operational parameters (fracturing fluid displacement and viscosity and perforation location) are the main controlling factors of fracture network propagation, whereas Poisson’s ratio of the coal seam has a relatively weak effect on the fracture network. As the elastic modulus difference between the roof and coal seam increases, the fracture network conductivity and simulated reservoir volume (SRV) first increase and then decrease. When the elastic modulus difference between layers is 10 GPa, the conductivity and SRV achieve their maximum values. With increasing displacement, the length, height and SRV of the fracture network increase linearly, but the conductivity decreases. Large displacement is beneficial to the formation of a complex fracture network in bright-type coal seams. The optimized fracturing fluid viscosity is 20 mPa·s. The optimal perforation location is near the formation interface. The results could provide theoretical guidance for the design and optimization of efficient fracturing of CBM reservoirs.","PeriodicalId":124387,"journal":{"name":"Volume 3: Fluid-Structure Interaction; High Pressure Technology","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114493719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are many factors that govern the type and severity of gaseous detonations in pressure vessels including gas composition, initial pressure, and ignition location within the pressure vessel. This paper addresses several of these factors, how they affect the resulting pressure transients in the vessels, and how the pressure transient loads can be applied to the Abaqus structural model. The method of load application is easily adapted to other FEA software packages. The structural integrity of the vessel is evaluated using the Abaqus Johnson-Cook plasticity model and associated strain limit damage criterion. The paper is specifically focused on pressure vessels where gaseous detonations have unique characteristics compared with more constrained space such as piping systems. A companion paper (PVP2022-84291) addresses the unique characteristics of gaseous detonations in piping systems and pipelines.","PeriodicalId":124387,"journal":{"name":"Volume 3: Fluid-Structure Interaction; High Pressure Technology","volume":"36 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123355237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Numerical simulation can represent a useful approach to investigate and predict such mechanisms. Nevertheless, the very high computational resources required by FSI simulations can represent a significant limitation in terms of industrial applications. From this point of view, simplified modelling approaches, when physically applicable, can represent an interesting compromise. This can be the case of slender structures (tubes, pins, rods, etc.) often encountered in nuclear power plants. In this paper, a 1D Euler-Bernoulli beam finite element model was implemented inside the CFD code code Saturne. The resulting fluid-structure coupled model is able to calculate the vibration response of a cantilever beam (a cylinder, for example) under a fluid flow, avoiding the necessity of CFD-FEM code coupling. The first part of the paper describes the model and its implementation: it allows to perform 2-way explicit fluid-structure coupling, using the Arbitrary Lagrangian-Eulerian approach in order to take into account the structure deformations. Validation test cases are presented in the second part of the paper, for a cylinder in static air and water and submitted to water cross-flow: frequency, damping, fluid forces and cylinder vibrations in the drag and the lift directions are analysed and compared to reference data.","PeriodicalId":124387,"journal":{"name":"Volume 3: Fluid-Structure Interaction; High Pressure Technology","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131907674","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This application involves a turbine style high-vacuum pump, known as a turbomolecular pump, that produces a high-vacuum atmosphere within a given volume that it is connected to. The basic design of the turbomolecular pump has a motor turned rotor with several turbine blades attached to it, and that spins at high rotational speeds, up to 60,000 revolutions per minute. The turbine blades are configured on the rotor to impact and move gas molecules axially through the pump and eventually to an exhaust location. In order to achieve a high pumping speed, the rotor needs to turn at very high rotational speeds. A turbine blade failure, therefore, can throw high-speed fragments against the turbine pump housing, and potentially breach the housing. The safety design objective is to keep all debris captured within the turbine pump housing as the pump rotor spins down from the blade failure event. The dynamic properties of the materials of construction are applied, along with the pertinent initial and boundary conditions to create a simulation model that predicts the results of this high-speed fragment impact case.","PeriodicalId":124387,"journal":{"name":"Volume 3: Fluid-Structure Interaction; High Pressure Technology","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127179717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pipeline vibration is the most important factor that involves the safety of the compressor. The pressure pulsation in the pipeline system is the core cause of the pipeline vibration. For the reciprocating compressors whose discharge pressure is lower than 35MPa, there are relatively complete analysis and measurement methods for pressure pulsation and pipeline vibration in API618. Hypercompressors are often accompanied by big pressure pulsation, far exceed the requirements of API618, but these devices can operate stably for many years, which thanks to detailed acoustic analysis and cyclic stress analysis. In this paper, a LDPE plant pipeline is researched. For security and operability, a non-invasive pressure pulsation measurement method based on the external surface strain of the pipeline is introduced. A detailed acoustic analysis model is established, and based on the pressure pulsation data of more than 60 measuring points arranged in the hypercompressor pipeline, the accuracy of acoustic simulation analysis is verified. The pulsation control components such as buffer tank and orifice are analyzed, the cause of vibration is stripped and analyzed so that targeted control measures can be developed, then some suggestions are given.","PeriodicalId":124387,"journal":{"name":"Volume 3: Fluid-Structure Interaction; High Pressure Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125531282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
