Natural convection of fluid with variable viscosity from a heated vertical wavy surface. (English) Zbl 0996.76081

Summary: The effect of a temperature-dependent viscosity on natural convection flow of viscous incompressible fluid from a vertical wavy surface has been investigated using an implicit finite difference method. We have focused our attention on the evaluation of local skin-friction and local Nusselt number. The governing parameters are Prandtl number, Pr, ranging from 1 to 100, the amplitude of the waviness of surface, \(\alpha\), ranging from 0.0 to 0.4, and the viscosity variation parameter, \(\varepsilon\), ranging from 0.0 to 6.
