平片型控制器湍流减阻的数值模拟

Numerical Simulation of the Turbulent Drag Reduction by Plate Manipulators

本文用数值方法求解了平片型控制器湍流减阻问题。出发方程和湍流模型分别采用部分拋物化的N-S方程和J-K模型。计算从控制器的上游开始,给出了单片装置及并排双片装置等两种典型的减阻结果,并和实验值进行了对比。

Numerical computation of the turbulent drag reduction by plate manipulators within the boundary layer is presented.The code is based on the partially parabolic Navier-Stokes equations together with the J-K turbulence model. Calculations start upstream of the manipulators including single device and tandem. The results obtained are compared well with the experiments.
