Abstract
En 中文
It is well-known that viscoelasticity plays a stabilising role in thin liquid film flow at moderate Reynolds numbers; which; however; cannot be resolved by current long-wave models. All these long-wave models can only predict the destabilising effect of viscoelasticity. This paper proposes a novel integral boundary layer model for a two-dimensional Oldroyd-B liquid film flow down a vertical plane. It consists of four dynamical variables – the film thickness errors against the full Navier–Stokes equations.
