任意Atwood数Rayleigh-Taylor和Richtmyer-Meshkov不稳定性气泡速度研究
The bubble velocity research of Rayleigh-Taylor and Richtmyer-Meshkov instabilities at arbitrary Atwood numbers
摘要
Abstract
We generalize the Layzer＇s bubble model to the cases of two-dimensional and three-dimensional analytical models of an arbitrary interface Atwood number and obtain self-consistent equations.The generalized model provides a continuous bubble evolution from the earlier exponential growth to the nonlinear regime.The asymptotic bubble velocities are obtained for the Rayleigh-Taylor（RT） and Richtmyer-Meshkov（RM） instabilities.We also report on the two-dimensional and the three-dimensional analytical expressions for the evolution of the RT bubble velocity.关键词
