[Abstract]:Based on TRIP3.0 software platform and multi-block grid technology, the effects of control equations and grid topology on the numerical simulation of DLR-F6 configuration are studied.The parameters of the numerical calculation are the same as those of the experiment, and the RANS/TLNS equation is adopted. The coarse, medium and fine meshes of O type and H type topologies are generated for simulation.The results are analyzed from three aspects: aerodynamic characteristics, pressure coefficient distribution curve and surface flow state.By comparing with the experimental data, it is shown that the calculation results obtained by using H-type topological mesh and RANS equation model are more accurate when small separated flow is simulated.
