Similarity Solutions for Heat Transfer in a Ostwald-De Waele Fluid Flow Past a Non-Linearly Stretching Surface
نویسندگان
چکیده
An analysis is performed to study the flow and heat transfer characteristics of a non-Newtonian Ostwald-de Waele fluid flow over a non-linearly stretching surface in the presence of internal heat generation/ absorption. The stretching velocity and the prescribed surface temperature are assumed to vary with a powerlaw distance from the slit. Using a similarity transformation the governing equations are reduced to a set of coupled ordinary differential equations and these equations are solved numerically by an implicit finite difference scheme known as Keller box method. Numerical solution is found to be dependent on six governing parameters, namely, the power law index, the velocity exponent parameter, the injection parameter, the temperature exponent parameter, the modified Prandtl number and the heat source/ sink parameter. Numerical computations are performed to understand the variations of linear and non-linearly stretching surface for different values of physical parameters to display the velocity and temperature profiles. The obtained numerical result shows that the injection parameter 0 w f < is to increase the velocity as well as the temperature and the suction parameter 0 w f > does the reverse. Results are compared with previously published work and are found to be in excellent agreement. 487 K. V. Prasad, et al., J. Comp. & Math. Sci.
