Unsteady mixed convection boundary layer flow from elliptic cylinder

Abstract

The unsteady mixed convection boundary layer flow of a Newtonian fluid near the region of the stagnation point over an elliptic cross section of a cylinder in both horizontal (blunt elliptic cylinder) and vertical (slender elliptic cylinder) is considered in this project. The governing system of higher order partial differential equations is reduced into a system of first order differential equations. Then, the transformed equations are solved numerically by Keller-box scheme. The numerical results are obtained for various values of the Prandtl numbers and parameter � (parameter for major and minor axes of the cylinder). Meanwhile, the features of assisting and opposing flow are investigated.
