Abstract The stability of the plane interface separating two viscoelastic (Walters B′) superposed fluids of uniform densities has been studied. The stability analysis has been carried out, for mathematical simplicity, for two highly viscoelastic fluids of equal kinematic viscosities and equal kinematic viscoelasticities. For the stable configuration, the system is found to be stable or unstable for the wave-number range k 〈 or 〉 (2ev′)-1/2, depending on kinematic viscoelasticity v′. However, the system is found to be unstable for the unstable configuration. The behaviour of growth rates with respect to kinematic viscosity and kinematic viscoelasticity are examined analytically.
