Academic studies started with empirical dilute-phase pneumatic conveying and, in order to produce better economic results in industrial settings, evolved to include energy efficiency techniques as a significant component. Much work has been done to understand and model pneumatic conveying systems; however, they are highly empirical and the conclusions are, in most cases, limited to a narrow range of experimental conditions. This paper introduces a systematic method to select the air pressure and flow necessary to operate an energy-optimized pneumatic conveying system. This method has been tested and applied to a pressure conveyor fed by a compact blow tank of 100 L in a 133 m long pipeline with a diameter of 3 inches conveying limestone. The tests demonstrated that it is possible to control this pneumatic conveying system with only two input parameters, while operating at the desired pressure and airflow and maintaining the respective conveying rate and power requirements.","PeriodicalId":50080,"journal":{"name":"Journal of Pressure Vessel Technology-Transactions of the Asme","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46304276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The internal crude oil generates an impact load on the inner wall under the action of the ship rolling motion, resulting in stress concentration or even cracking on the head, which seriously threatens the safety of offshore oil mining and FPSO workers. Take No. 118 FPSO pressure vessel as an example, the researches are carried out by considering the actual sea states in the South China Sea. The ship motion response equations are established; a dynamic evaluation study is carried out on the safety evaluation and analysis of the key structure of the pressure vessel based on FLUENT numerical simulation calculations, the results show that the key structure of the pressure vessel Safety, its stress value is positively correlated with sea state level and filling coefficient. The pressure vessel scale model experiment was carried out with an electric six-degree-of-freedom experimental platform, and the change rule of the measured point test was basically consistent with the simulation value, and the numerical error was only 11.804%, which verified the accuracy of the simulation model.

Their accuracy is usually characterized by so called “model error” notion. The latter is established as the averaged deviance of experimental data from the calculated results. In fact, the determined in such way model error is partly related to the validity and range of the chosen experimental data. The idea of our work is to introduce the notion of “targeted model error”. It is expected to characterize the accuracy of given formula for the particular defect only with given ratio of its dimensions, which is named as the “point of interest”. So, every experiment can give the contribution to the targeted model error according to its weight on the point of interest. These weights are subjectively established based on the difference between the dimensionless residual strengths calculated for the point of interest and for the real defect dimensions of the considered experiment. Practical examples of determination of the targeted model errors are performed for the ratios of the defect depth to wall thickness equal to 0.5, 0.6, 0.7 and 0.8 for three well-known formulas - ASME, PPCORC and O-formula.","PeriodicalId":50080,"journal":{"name":"Journal of Pressure Vessel Technology-Transactions of the Asme","volume":"1 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"63503691","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The displacement of any generic point on the structural panel is derived using the third-order shear deformation theory (TSDT). Moreover, the direct iterative method has been adopted to obtain the nonlinear eigenvalues in conjunction with the isoparametric finite element (FE) steps. The present analysis includes the effect of temperature and the temperature-dependent composite elastic properties on the thermoelastic frequencies. This study intends to establish the Green- Lagrange type of nonlinear strain's efficacy in computing the nonlinear frequency of layered structure with and without cutout instead of von-Karman strain kinematics. The numerical model's validity has been established by comparing the results to previously published results. In addition, experimentally obtained fundamental frequency values of few modes are compared to numerical proposed numerical results under the thermal loading. Finally, the effects of cutout (shape and size) and the associated structural geometrical parameters on the nonlinear thermal frequency responses of the laminated structure are expressed in the final output form.","PeriodicalId":50080,"journal":{"name":"Journal of Pressure Vessel Technology-Transactions of the Asme","volume":"1 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41449395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Major flaw dimensions (depth or height and length) are typically characterized assuming the flaws to be contained entirely within a bounding rectangle through a procedure known as flaw idealization. In fracture mechanics based calculations, flaws are often assumed to be (semi-)elliptical when evaluating possible interaction. This paper investigates the implication of this simplification for the specific case of two identical co-planar surface breaking flaws. Two flaw shapes are considered and compared: semi-elliptical and canoe-shaped (quarter-circular ends with constant depth elsewhere). Especially for long and shallow flaws, the canoe-shaped configuration best approximates the bounding rectangle, whereas the semi-elliptical shape only touches the bounding rectangle at three points (deepest point and two points at the surface). Several flaw dimensions and spacing distances are studied through an extensive parametric study comprising both linear elastic and elastic-plastic finite element simulations. The results, evaluated in terms of stress intensity factor (SIF) and J-integral, show that the flaw shape idealization, particularly for long and shallow flaws, can significantly affect the degree of interaction between identical co-planar flaws. The inconsistency between semi-elliptical and canoe-shaped flaw shapes is observed in a linear elastic analysis and becomes more pronounced at higher loading levels evaluated in elastic-plastic analyses","PeriodicalId":50080,"journal":{"name":"Journal of Pressure Vessel Technology-Transactions of the Asme","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45790492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Amongst the primary concerns for these tubes is the deposition of ash particles on the tube surface, leading to the reduced thickness of the tube due to material corrosion, consequently causing early creep failure of the component. In this research, a novel tube design has been proposed which resembles a teardrop or ogive shape to reduce the drag and concurrently improve the creep life of the superheater tubes. To administer the practicality of novel tubes, metal Additive Manufacturing, for instance, Laser-Powder Bed Fusion, has been proposed. These unconventional designs were assessed and compared with the baseline circular tube design for mechanical design requirements and the particle and flue gas flow characteristics around the differently shaped tubes. A thermo-mechanical Finite Element Analysis (FEA) was performed for hoop stress calculations. This study also emphasizes on effect of circumferential thermal variation on hoop stress distribution in tubes. Therefore, a detailed 2D thermal simulation has been performed to report the circumferential thermal variation on the tube. A Computational Fluid Dynamics (CFD) analysis coupled with particle tracing was performed for gas flow visualization and particle tracing around the proposed shapes and baseline circular-shaped tube design. The Schlieren Optic setup was built and leveraged for qualitative validation of the proposed design. The complete design methodology established in the paper shows teardrop-shaped tubes better in terms of drag and creep life in contrast to the circular-shaped tube.","PeriodicalId":50080,"journal":{"name":"Journal of Pressure Vessel Technology-Transactions of the Asme","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2022-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44232309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
