| description | The significance of this study pertains to the development of alternative energy sources, including solar panels, the optimization of thermal management in contemporary computer system microcomponents, safety protocols for nuclear reactors. The investigation addressed the numerical simulation of natural convection executed in a two-dimensional approximation. A comparative analysis of the mean temperature and vertical velocity component profiles derived from these simulations indicated that the OFv8 and OFv9 versions of OpenFOAM yielded congruent results, whereas the outputs from OFv7 deviated. It was observed that the SGG model in OFv7 provided velocity component profiles at mid-height that were more accurate compared to the LRR model. Conversely, for the OFv8 and OFv9 versions, the accuracy of the numerical results declined. It was demonstrated that for the SGG model, the accuracy of the velocity profile is enhanced when employing the bounded Gauss limitedLinear 1 scheme for discretizing the convective term of the equations for R and ε, as opposed to using the upwind scheme. OFv7, OFv8, and OFv9 versions of the OpenFOAM suite were found to underestimate the maximum kinetic energy and Reynolds stress near the cold, left cavity wall. The findings are applicable to mathematical modeling of heat and mass transfer processes. |
