Explicit Solutions of a Gravity-Induced Film Flow along a Convectively Heated Vertical Wall

Abstract EN

The gravity-driven film flow has been analyzed along a vertical wall subjected to a convective boundary condition.

The Boussinesq approximation is applied to simplify the buoyancy term, and similarity transformations are used on the mathematical model of the problem under consideration, to obtain a set of coupled ordinary differential equations.

Then the reduced equations are solved explicitly by using homotopy analysis method (HAM).

The resulting solutions are investigated for heat transfer effects on velocity and temperature profiles.
