The proposed research is an analytical/numerical investigation of the fundamentals of heat/mass transport into solitary waves on the surface of a liquid film falling down a vertical substrate in the presence of chemical reactions taking place in the film. Wave formation on a falling film is characterised by a transition from short, near-sinusoidal capillary waves to a train of long, solitary waves with large tear-drop humps preceded by short, front-running capillary waves. Such large amplitude solitary waves possess a recirculation zone with closed streamlines responsible for most of the heat/mass transport into falling films. Our study will reveal the generic features of the effect of chemical reactions on heat/mass transport enhancement due to strong advection mixing in the recirculation regions. We will also examine the effect of perturbing the recirculation zone via appropriate time/spatially-varying forcing resulting in additional enhancement due to chaotic mixing.
