Abstract
The stability of the plane interface separating two viscoelastic superposed fluids of uniform densities has been studied. The stability analysis has been carried out, for mathematical simplicity, for two highly viscous fluids of equal kinematic viscosities. It is found that the system is stable for stable configuration and unstable for unstable configuration. The behaviour of growth rates with respect to stress relaxation time and strain retardation time parameters are examined analytically.
