Thus computational fluid dynamics (CFD) becomes an important and efficient tool for hypersonic vehicle design.
Flow field simulation with CFD can provide much more data of different conditions than experiments with much higher accuracy than engineering calculation.
Hypersonic flow field simulation Hypersonic flow around a three-dimensional vehicle is complex due to strong shocks and their coupling effects with the viscous boundary layer.
The total number of grid nodes is above 3 million. 2.3 Simulation results The flight conditions under which flow field simulations implemented are: Ma=6.0, altitude=25Km, angle of attack α=-2°, 0°, 2°, 4°, 6°, 8°, angle of elevator deflection δ=-3°, -1.5°, 0°, 1.5°, 3°.
Therefore, the method of flow field numerical simulation and the response surface model presented can improve aerodynamic characteristics analysis reliably and efficiently.
