Fluid Instabilities in Different Conditions

Interfacial fluid instabilities are one of the open challenges to the scientists and researchers of fusion community and Astrophysicists. The most common fluid instabilities are RayleighTaylor (RTI) Richtmyer-Meshkov (RMI) Kelvin-Helmholtz (KHI) according to the name of the discoverers. However these instabilities arise at the interface of two fluids under different physical conditions. RTI occurs when a density gradient (∇ ρ) is subjected to an acceleration by an antiparallel pressure gradient (∇ P) in the presence of perturbations i.e. when ∇ ρ - ∇ P
