Abstract
A mathematical model of falling film absorption of H2O by LiBr aqueous solutions which considers wavy regimes has been implemented. The model is semi-empirical, based on Navier Stokes equations together with energy and mass species simplified under the boundary layer hypotheses. The coupled equations are solved by means of finite difference method in a step by step procedure. The wavy profile is introduced by solving Free Surface Deflection Equation in each grid step, the smooth film thickness i...
