Abstract
This investigation focuses on how the waviness of one of the walls affects the flow and thermal-mass exchange of a completely developed free convection stream of a viscous, incompressible fluid that is constrained between two long, vertical walls in a permeable medium. The walls exhibit different shapes- one is wavy, the other is flat and the movement of both the walls is caused by variations in wall temperatures and concentrations. The emphasis has been on elucidating the Soret and Dufour impacts pertaining to heat sources and chemical reactions. The governing equations are accurately modeled through a series of regular differential equations generated by an analogous transformation. These equations are then solved using MATLAB’s advanced numerical method. A thorough analysis of the distributions of velocity, temperature and concentration has been conducted taking into account a range of physical parameters. Additionally, comprehensive tables have been compiled that demonstrate the variations in skin friction, Nusselt number and Sherwood number according to various management parameters at both walls. The current outcomes are compared to previously released works and are deemed to be a great addition.
