A three-dimensional fully parameterized beam element based on the absolute nodal coordinate formulation (ANCF) is used to account for the rotary inertia of the rotating pipe model. The rotation of the pipe is imposed through a rotation matrix at the top node and transmitted through the twist of the pipe along its length, therefore accounting for the nonlinear coupling of bending and torsional deformations. In addition , three-dimensional components of hydrodynamics forces in relation to the inflow velocity of water, rotational velocity, and orientation of the pipe were computed using ANSYS Fluent . The obtained forces are applied as an external force vector on the pipe model. Through a comparison of simulation results and experimental results, the applicability of the presented model is confirmed.","PeriodicalId":50302,"journal":{"name":"International Journal of Offshore and Polar Engineering","volume":"163 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135347825","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}

This paper takes NACA66 (mod) two-dimensional hydrofoil as the research object and uses the open-source software OpenFOAM to simulate the sheet cavitation and sound field. The turbulence model is DDES, and the cavitation model is the Schnerr-Sauer model. The sound field is predicted by the FW-H formulation. Unlike the traditional method, this paper solves the quadrupole term (nonlinear term) by direct volume integration, so the nonlinear term can be predicted more accurately. At the same time, a new method of changing sound wave velocity is proposed considering the two-phase medium problem caused by cavitation. Four methods are compared, including two-phase volume integration, direct volume fraction, object surface integration, and penetrable formulation. It is found that the influence of two-phase flow is greater near the closure area of the cavity, which needs to be considered separately. The linear sound shows dipole directivity and the nonlinear component exhibits quadrupole characteristics.","PeriodicalId":50302,"journal":{"name":"International Journal of Offshore and Polar Engineering","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135347830","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}

In wind farms where wind turbines are grouped in arrays, under unfavorable conditions, downstream wind turbines will operate in the wakes of upstream turbines, and thus will harm the overall efficiency of wind farms. Accurately predicting the performance of downstream turbines and the interactions between multiple turbine wakes are crucial to the design of more efficient wind farms because it forms the cornerstone of wind farm layout optimization algorithms. In the present study, we perform CFD simulations for the NTNU Blind Test 2 experiment in which two turbines were placed in a closed-loop wind tunnel and operating in line. The Reynolds-Averaged Navier Stokes (RANS) equations with the k-ω SST turbulence model are adopted in the simulations. For each of the two wind turbines, geometries including the blades, hub, nacelle, and tower are fully resolved. The Moving-Grid-Formulation (MVG) approach with a sliding interface technique is leveraged to handle the relative motion between the rotating and stationary portions of the wind turbines. In the simulations, the values of tip-speed ratio (TSR) for the upstream and downstream turbines are 4 and 6, respectively. The CFD-predicted thrust and power coefficients are obtained under an inlet velocity of 10 m/s and are compared against the experiment results. In addition, the wake structures of the two wind turbines are also visualized and discussed.","PeriodicalId":50302,"journal":{"name":"International Journal of Offshore and Polar Engineering","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135347827","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 creep rate at the crack tip is used to characterize the driving force of EAC, and the creep rate is used to replace the strain rate at the crack tip in the Ford–Andresen model, which more effectively reflects the effect of cold working on a driving force of crack growth rate. Results show that the yield strength of 316L SS will increase the driving force of crack growth, whereas the hardening exponent will reduce the driving force. Both cold working and hardening at the crack tip can increase the driving force of crack growth and intensify crack growth. However, a sudden change of load can also produce residual compressive stress at the crack tip, which can inhibit crack growth.","PeriodicalId":50302,"journal":{"name":"International Journal of Offshore and Polar Engineering","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135347822","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}
