Abstract： We present a systematical numerical study of the effects of adiabatic exponent γ on Richtmyer--Meshkov instability (RMI) driven by cylindrical shock waves, based on the γ model for the multi-component problems and numerical simulation with high-order and high-resolution method for compressible Euler equations. The results show that the RMI of different γ across the interface exhibits different evolution features with the case of single γ. Moreover, the large γ can hold back the development of nonlinear structures, such as spikes and bubbles.
