虽然主动流动控制是控制飞行器和翼型上流动分离的一种既定方法，但执行机构的设计通常是通过反复试验来完成的。本文介绍了用于不可压缩雷诺平均N-S方程控制的非定常湍流最优控制的离散和连续伴随流动求解器的发展。将这两种方法应用于具有吹吸式主动流量控制的测试案例，并就计算梯度的准确性进行了比较。
While active flow control is an established method for controlling flow separation on vehicles and airfoils, the design of the actuation is often done by trial and error. In this paper, the development of a discrete and a continuous adjoint flow solver for the optimal control of unsteady turbulent flows governed by the incompressible Reynolds-averaged Navier-Stokes equations is presented. Both approaches are applied to testcases featuring active flow control of the blowing and suction type and are compared in terms of accuracy of the computed gradient.
