Transonic flow reconstruction by an adaptive prop er orthogonal decomp osition hybrid mo del
A proper orthogonal decomposition (POD) based hybrid surrogate model and the applications to transonic flow reconstructions are presented in the paper. In the implementations, the radial basis function (RBF) model response instead of the least-square linear regression is employed in order to improve the coefficients of POD basis modes;moreover, an adaptive sampling strategy with both the model response error and sample independence taken into account is studie…查看全部>>
