This project is one of the five projects of the 973 program “Study on key basic problems of aerodynamics and flight control covering flow regimes for aerospace craft”(No.2014CB744100), and the purpose of this project is to study the complex flow mechanism and numerical simulations of aerodynamics and thermodynamics of multi-physics field covering flow regimes of large aerospace craft. Based on the moving grid technique and the numerical simulation method of unsteady N-S equations, the numerical simulation technique applied in the study of unsteady aerodynamics of active moving boundaries in large field and wide range of velocity field will be established, and the technique of generation of deformable moving grid will be developed. We will develop the parallel codes to solve the N-S equations for the interactions of unsteady shocks with multi-physics processes of active morphing surface, and doing direct numerical simulations of the interactions of unsteady shocks with boundary layers and vortices in the typical super-hyper-sonic flow of active morphing body surface, to reveal the details of flow field and the interactions of multi-physics processes. On the other hand, we will also explore the experimental techniques of flow visualization and measurement for hyper-sonic low density wind tunnel.
