Diversified utilizations of permeable domains are found in cooling systems, gas recovery, and insulation engineering. Therefore, this research focused on investigating the heat transport aspects imparted by buoyantly driven flow a viscous fluid saturated L-shaped enclosure. Darcy Brinkman-Forchheimer model is considered present pagination to envision permeability aspects. In addition, entropy generation encapsulate disordered form system. study, an l-shaped domain with heated steps insulated horizontal boundaries was entertained, while vertical walls kept cold. Non-persistent buoyancy forces employed elucidate impact gravitational forces. The mathematical formulation problem examined dimensionless coupled partial differential system after normalizing variables. Subsequently, Galerkin finite element method implemented using commercial multigrid software (COMSOL) find solution constructed problem. influence included parameters related distributions quantities interest comparative sense evaluated sketches tables. A comparison results along grid-independent test also performed ensure reliability computational procedure computed outcomes. It inferred that total averaged Nusselt number increase as increases 21.39% 10.76%, respectively, whereas Bejan exhibits opposite trend. Raising aperture ratio enclosure reduction flux coefficient, ECOP indicates entropy.

Abstract This research examines the influence of heat source/sink and activation energy on ternary nanoliquid flow due to rotating cone with wall‐deforming boundary circumstances in porous media. The suspension differently shaped nanoparticles base liquid is also considered modelling. development layer structure may be determined by analysing von Karman's classic deformable revolving disk flow. Therefore, engineering community can easily identify significant physical characteristics a certain apex angle using multiplication factor associated spinning governing partial differential equations are converted ordinary help similarity variables. obtained numerically solved Galerkin finite element technique. Graphical depictions illustrate impact various dimensionless factors different profiles. deformation‐to‐rotation ratio fluid velocity profiles shown for both stretching shrinking scenarios. As parameter values increase, temperature rises. concentration profile decays chemical reaction intensifies parameter.
