The transformation group theoretic approach is applied to perform an analysis of unsteady free convection flow over a vertical flat plate immersed in a power law fluid. The thermal boundary layer induced within a vertical semi-infinite layer of Boussinseq fluid. The system of governing partial differential equations with boundary conditions reduces to a system of ordinary differential equations with appropriate boundary conditions via two-parameter group theory. The obtained ordinary differential equations are solved numerically for velocity and temperature using the fourth order Runge-Kutta and shooting method. The effect of Prandtl number and viscosity index (n) on the thermal boundary-layer, velocity boundary-layer, local Nusselt number, and local skin-friction were studied.

Abstract Steady free convection laminar boundary-layer flow subject to mixed thermal boundary conditions along a heated vertical plate immersed in a quiescent power-law fluid is investigated. Similarity solutions are obtained numerically for the boundary-layer velocity and temperature profiles. The effects of flow behavior index and the generalized Prandtl number on the surface shear stress and heat flux are determined.
