摘    要:为探讨适用于整车风洞的分布抽吸率,采用计算流体力学(Computational Fluid Dynamics,CFD)方法研究经边界层控制后的试验段流场.针对不同分布抽吸率下的试验段,利用FLUENT对流场进行模拟,然后计算边界层位移厚度、静压因数和气流偏角.二维和三维的数值模拟结果均表明,试验段边界层的位移厚度随分布抽吸率的增加而减小;当分布抽吸率达到某一数值后,若继续增大,那么边界层的位移厚度将基本保持不变.研究结果对风洞建设及试验时分布抽吸率的选取有参考意义.

关 键 词:分布抽吸  抽吸率  整车风洞  试验段  计算流体力学  数值模拟  Fluent

Abstract:To find the appropriate distributed suction rate for full scale wind tunnel,the flow field controlled by boundary layer in test section is studied by using Computational Fluid Dynamics(CFD) method.With the test sections under different distributed suction rate,the flow fields are simulated by using FLUENT and the displacement thickness of boundary layer,pressure factors and yaw angle are calculated.The results of 2D and 3D numerical simulation indicate that the boundary layer displacement thickness of test ...
