ABSTRACT: The growth of multi-mode Richtmyer-Meshkov instability under multiple impingements
and the effect of initial shock strength on the growth of RMI are numerically
investigated. We obtain the time evolution of turbulent mixing zone width for
initial shock with different strength. The results show that the turbulent
mixing zone width grows in a different manner at different stage but strictly
in a similar way for the initial shock with different strength. Also, the
initial shock strength has a significant effect on the growth rate of turbulent
mixing zone width, especially before reshock, but can not change the growth
laws in the whole process.
