在本文中,我们提出了一种基于连续伴随计算的形状优化方法。如果使用精确的离散伴随方程,则所得公式产生精确的离散约化梯度。我们首先介绍了伴随的形状导数计算在Banach空间设置。然后将该方法应用于非定常Navier-Stokes方程。最后给出了一些数值结果。
In this paper we present an approach to shape optimization which is based on continuous adjoint computations. If the exact discrete adjoint equation is used, the resulting formula yields the exact discrete reduced gradient. We first introduce the adjoint-based shape derivative computation in a Banach space setting. This method is then applied to the instationary Navier-Stokes equations. Finally, we give some numerical results.
