Flow and Heat Transfer on a Continuous Flat Surface Moving in a Parallel Free Stream with Variable Fluid Properties

摘要

Boundary layer flow and heat transfer on a continuous flat surface moving in a parallel free stream with variable fluid properties are investigated. The similarity solution is used to transform the problem under consideration into a boundary value problem of coupled ordinary differential equations. Numerical results are carried out for various values of the dimensionless parameters of the problem. The results have demonstrated that the assumptions of constant properties may introduce severe errors in the prediction of surface friction factor and heat transfer rate. For the same Reynolds numbers, Prandtl numbers, heating parameter, temperature exponents for viscosity and thermal conductivity parameters, and the same velocity difference |U_w-U_infinity|, larger skin friction, and heat transfer coefficient results for U_w>U_infinity than for U_w
