RADIATION EFFECT ON NATURAL CONVECTION LAMINAR FLOW ALONG A VERTICAL WAVY SURFACE (original) (raw)
The effect of thermal radiation on a steady two-dimensional natural convection laminar flow of viscous incompressible optically thick fluid along a vertical wavy surface has been investigated. Using the appropriate variables; the basic equations are transformed into the local non-similarity boundary layer form and then solved employing the Keller-box scheme of finite difference method. Numerical results are presented by streamline, isotherms, velocity and temperature distribution of the fluid as well as the local heat transfer rate in terms of local Nusselt number and average rate of heat transfer for a wide range of Planck number R d and the surface heating parameter θ w . The present numerical result shows excellent agreement with the published results when the effect of thermal radiation was passed over.
