A New Upper Bound for the Largest Growth Rate of Linear Rayleigh--Taylor Instability
Changsheng Dou, Jialiang Wang, Weiwei Wang
We investigate the effect of surface tension on the linear Rayleigh--Taylor (RT) instability in stratified incompressible viscous fluids with or without (interface) surface tension…
