Temporal evolution of periodic disturbances in two-layer Couette flow
The time-dependent motion for a two-layer Couette flow consisting of fluids of different viscosities is simulated numerically by using an algorithm based on the volume of fluid method. Interfacial tension is included via a continuous surface force algorithm. The algorithm is fine-tuned to handle the motion which is driven by a shear-induced interfacial instability due to the viscosity stratification. The code is validated against linear theory.
