Penggunaan Metode Perturbasi Homotopi pada Penyelesaian Persamaan Aliran Busa Cair

Abstract

Aqueous foam drainage inside Plateau border affects the structure of foam. Foam becomes fragile when it dries due to reduction of liquid flow. The distribution of liquid flows inside Plateau border which affects the structure of foam can be described mathematically in form of aqueous foam drainage equation. In this paper, aqueous foam drainage equation is solved by homotopy perturbation method. In homotopy perturbation method, the solution of this equation assumed in the form of power series. By giving the exact initial approach, the solution of this equation using homotopy perturbation method can estimate the exact solution with a small error rate.
