Abstract
A numerical simulation of steam absorption in LiBr aqueous solution is performed in order to investigate the effects of solitary wave. The simulation is based on a finite difference method and the governing equations are discretized on the staggered grid fixed on the physical space with constant mesh sizes. Solitary waves are generated by periodically disturbed inflow boundary. Result shows that solitary wave produces recirculation in the solution and this recirculation moves the cool and rich LiBr solution to the interface and enhances the absorption. Simulation result is compared with the smooth film and shows that wavy film provides higher absorption rate than that of smooth film.
