Abstract: Mixed convection in a wavy enclosure driven by a lid and including rectangular shaped blocks at various positions is the focus of this paper's simulation investigation. In this investigation, we also looked at how the heat transfer enhancement changed depending on the orientation of the heated block in relation to the stream. The control equations for mass, thermal energy, and Navier-Stokes are solved numerically using the Galerkin weighted residual finite element method. The enclosure contains two rectangular shaped heated blocks strategically positioned at varying heights - one set closer to the lower section of the enclosure, another situated at the mid-section of the enclosure and final set closer to upper wavy surface. The thermal insulation property of the wavy top wall, coupled with active heating of the bottom wall and blocks, creates a dynamic convective environment. Also, the lid-generated flow is driven by the left wall moving upwards and the right wall moving downwards. Richardson number impacts on streamlines, isotherms, dimensionless temperature, velocity profiles, average Nusselt numbers, and other characteristics are investigated in this study. Visualizations of these impacts are made possible using graphics. Inside the container, two eddies spun counterclockwise in every instance. Regardless of other factors, a higher rotating speed yields better performance. Enhanced heat transport would also be the outcome of a well-balanced set of regulating factors.
