review text: We suggest a new numerical simulation model and a theoretical method for domain decomposition hybrid combination of finite-difference method and vortex method. Specifically, the full flow field is decomposed into two domains. In the regions of \(O(R)\) near the body surface (\(R\) is the characteristic dimension of body), we use the finite-difference method to solve the Navier-Stokes equations and in the exterior domain, we take the Lagrange-Euler vortex method. The results show that the method of the present paper has the advantage of finite-difference solution for Navier- Stokes equations in precisely predicting the fine structure of flow field, as well as the advantage of vortex method in efficiently computing the global characteristics of the separated flow.
