On the Implications of Exponentially Decaying Internal Heat Generation on Mixed Convection Flow from a Vertical Porous Plate Influenced by Hydrodynamics and Thermal Partial Slip
摘要
This article contains crucial details about how internal heat generation affects mixed convection slip flow past a vertical plate. The simplified first-order differential equations are integrated with Maple Software 2022. One of the most important discoveries is that internal heat generation acts as a barrier to stop heat from flowing from the left to the right plate edge. However, this could be averted by considering strong mixed convection to covect away the heat conducted through the left plate surface and the internal heat generated. But for weak mixed convection, the movement of the fluid from the left to the right surface is achievable even with minimal internal heat generation. Since the right plate surface temperature is warmer (higher) than the left plate surface, the flow properties, in this case, are also affected by the internal heat generation, which also causes the reverse heat flow from the plate. Particle injection could also be used to avert unwanted reversed flow for various hydrodynamic slip conditions considered. Research relevance Internal heat generation can be used in heat transmission, nuclear reactors, post-accident heat removal operations, modeling of the combustion process, production of metal waste from nuclear fuel, and phase transition. However, the analysis of internal heat generation is influenced by the plate surface. The constant or convective boundary conditions were taken into account by various previous researchers. In this communication, momentum and thermal partial slip conditions are applied to the plate surface. The fundamental novelty of this article is the combination of internal heat generation, hydrodynamics, and thermal partial slip conditions.
