Numerical investigation of oscillatory instability in shock-induced combustion around a blunt body

The basic characteristics of oscillatory instabilities of shock-induced combustion around a spherical projectile flying at hypersonic speed is investigated on the basis of numerical simulation using a two-step chemical reaction model. A series of simulations is conducted to understand the mechanism of these oscillatory instabilities. The oscillatory instabilities are clearly observed when the projectile radius is about 7.5-10 times the induction length
