基于大涡模拟的螺旋桨梢涡数值分析
Numerical analysis of propeller tip vortex based on large eddy simulation
摘要
Abstract
By using the overset grid technique and the large eddy simulation (LES) method ,the veloc-ity field and the vorticity field of the propeller were calculated by solving the Navier-Stokes equations based on the STAR-CCM + software ,and the vortex morphology of the propeller under different speeding coefficients was compared .Numerical results show that the LES based on the orthogonal grid can simulate the tip vortex morphology of the propeller well ,and the tip vortex intensity of the propeller increases and appears to be disturbed at low speed coefficient as,while it shows a more regu-lar spiral scroll shape at high speed coefficient .关键词
