The use of homotopy methods for solving nonlinear foam drainage equation

摘要: Foaming occurs in many distillation and absorption processes. The drainage of liquid foams involves the interplay gravity, surface tension, viscous forces. In this paper, nonlinear foam equation is solved by using Adomian's decomposition method, modified variational iteration homotopy perturbation method analysis method. existence uniqueness solution convergence proposed methods are proved details. Finally an example shows accuracy these methods.
