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