Abstract

•Stability analysis of stratified flow via the Two-Fluid (TF) model is revisited.•The required closure relations are critically examined and new ones are suggested.•The TF model is able to reproduce the exact long wave neutral stability curves.•The role of the ‘sheltering force’ due to wave induced shear stresses is quantified.•A simple closure relation for the ‘sheltering’ term in the TF model is provided.
