Study on the unsteady aerodynamic heating of the oscillating model

摘要：

　　A numerical method is developed for studying the influence of the oscillating model to the aerodynamic heating.By using of the method of rigid dynamic grid and Arbitrary Lagrangian-Eulerian(ALE)formulation,a computer code is developed which could be applied to numerical simulate the unsteady aerodynamic heating of the oscillating airfoil models for hypersonic flow condition.The purpose of this study is to investigate the effects of the unsteady flow on the distribution of the heat flux.By comparison with the steady flow field,it shows that the head has little effect,while other part has a significant impact.
