Thermosolutal Convection in a Tilted Porous Parallelogrammic Enclosure with Discrete Heating and Salting

The current analysis addresses the tilt-angle impacts of an inclined parallelogram-structure geometry and discrete heating/salting-cooling combinations on the thermosolutal flow as well as associated heat and mass transport rates. The tiled boundaries are assumed to have a thermal-solute source-sink arrangements with different sizes placed along various positions of the inclined wall. Adopting the Darcy model for stream function-based model equations for flow motion and transient energy as well as solutal equations forms the complete model description of the chosen problem. The flow, thermal, and solutal processes have been discussed using streamlines, isotherms, and isoconcentrations; however, the heat and mass dissipation rates are estimated using Nusselt and Sherwood numbers. Numerical simulations effectively predict the impacts of sidewall tilt angle and discrete heating-salting on the thermosolutal flow, thermal and concentration distributions, and thermal and mass transfer rates for wide ranges of different parameters.
