Abstract:
The flow field of a reverse jet engine during landing is numerically calculated with Fluent software. The shape of the computational domain is changed with the relative position of ground and engine. In order to assure the accuracy of calculation, the dynamic mesh technology must be used. The basic methods to realize the mobile grid are described in this paper. The unsteady flow field numerical calculation during the engine landing is achieved by using the methods of grid spring-based smoothing motion and region face remeshing. The static pressure field and velocity field of the jet flow field generated the engine landing. In comparison with the steady calculation of flow field, the results show that the dynamic mesh is applicable
