Group analysis for natural convection from a vertical plate

The steady laminar natural convection of a fluid having chemical reaction of order n past a semi-infinite vertical plate is considered. The solution of the problem by means of one-parameter group method reduces the number of independent variables by one leading to a system of nonlinear ordinary differential equations. Two different similarity transformations are found. In each case the set of differential equations are solved numerically using Runge–Kutta and the shooting method. For each transformation different Schmidt numbers and chemical reaction orders are tested.
