Title: Natural convection flow of two-phase dusty gas with variable thermophysical properties along a vertical wavy surface
Language (ISO): en
Abstract: The purpose of the present study is to establish the detailed parametric solutions for laminar natural convection flow of two-phase dusty fluid moving along a vertical wavy plate. Typical sinusoidal surface is used to elucidate the heat transport phenomena for the carrier gas having variable thermophysical properties. The governing equations are cast into a system of parabolic partial differential equations by using set of continuous transformations and then the resulting system is integrated through implicit finite difference method. In order to ensure the accuracy, the present numerical results are also compared with the available published results and good compatibility is found between the present and previous results. It is showed that mass concentration parameter, D_p, and the variable thermophysical properties extensively promotes the rate of heat transfer near the uneven surface. It is also established that amplitude of the wavy surface enhances very drastically, which is also due to the variable properties of the fluid.
