摘要
Abstract
The CFD simulation software STAR-CCM + is used to simulate the wake field of the MIRA model.The flow mode of the tail is controlled by the active control drag reduction technique with steady jet.We studies the method of jet reduction and uses the SST k -ω turbulence model to simulate the tail flow field of the square-back MIRA model.The position on the tail is studied.It finds the best reduction case of each position.The positions of optimal reduction is combined to achieve the maximum degree of drag reduction.Then it analyzes the variation of the tail vortex.It is found that the pressure of the model can be changed by controlling the separation vortex of the tail,so as to reduce the pressure resistance of the model and realize the purpose of drag reduction.关键词
