Boundary Layer Flow and Heat Transfer of a Nanofluid over a Moving Surface with Internal Heat Generation

摘要

The problem of steady laminar boundary layer flow over a fixed or moving flat surface by considering the effect of internal heat generation is studied in this paper. By using a similarity transformation, the partial differential equations are transformed into ordinary (similarity) differential equations. The transformed equations are solved numerically for copper, Cu nanoparticles, in the water based fluid with Prandtl number Pr = 6.2. These equations along with the corresponding boundary conditions are solved numerically using a numerical bvp4c Matlab program. The effects of internal heat generation on the velocity and the temperature profiles are illustrated. The results also indicate that the dual solutions exist when the surface and the free stream move in opposite directions.
