各种间隙比下海底管线绕流二维数值模拟与实验研究
Two-Dimensional Numerical Simulation and Experimental Study of Flow Around Submarine Pipeline at Various Gap-Ratios
摘要
Abstract
The characteristics of flows around the submarine pipeline at various gap-ratios are studied by the numerical and experimental approaches. The 2-D numerical model which uses finite difference method to discrete the standard k-ε turbulence equations and governing equations is solved by Generalized Minimum RESidual (GMRES) algorithm . In the experiments, the velocity of cross-sections are investigated by ADV. The characteristics of vortex at various gap-ratios were analyzed. In addition, the velocity changes of wake flow were studied at different gap-ratios. The simulation result is agreement with the experimental result. The achievement in this paper sets the stage for the research on the submarine pipeline's protective measurements.关键词
