| Abstract: | The unsteady characteristics of flow around an oscillatingelliptical slender body are studied by numerical method. The unsteadycompressible full Navier-Stokes equations are solved by time-accurateimplicit TVD algorithm. Through the numerical simulation, the unsteadyevolution of shock and separation during the oscillation of missile arepresented. Also the effect of reduced frequency and compressibility areinvestigated. |
