Adding additive with nano‐sized and considering porous media, new container has been generated and numerical technique was employed to model the convection process of cooling the four lobed surfaces which is situated inside three lobed tanks. Uniform flux was considered for four lobed surfaces while the outer surface is cold wall. With neglecting advection term due to employ of Darcy law, simpler form of momentum equations was appeared with is coupled with source term of magnetic field. Moreover, mixture model for testing fluid was applied with incorporating the efficacy of shape of nanopowders. Dispersing nanoparticles causes augmentation in Nu around 41.33% because of augmenting conductivity. The elevation of Ra makes Nu to increase around 38.98% in absence of Ha while this augmentation reaches to 1.54% in existence of Ha which means that domination of conduction in appearance of MHD. Augmenting shape parameter leads to rise of Nu around 11.72% while increment of Ha causes this function to reduce around 11.73%.

Heat exchangers are crucial in transferring heat and finding applications across various industries. Numerous strategies have been devised to improve and optimize the heat transfer process within these systems. Among these, passive methods have garnered significant attention for their ability to operate without external power consumption. This article examines the recent experimental and computational studies conducted by researchers since 2018 on passive enhancement techniques, especially twisted tape, wire coil, swirl flow generator, and others, to boost the thermal efficiency of heat exchangers and aid designers in adopting passive augmentation methods for compact heat exchangers. Recently, researchers' new class of flow maldistribution devices, referred to as swirl flow devices, has gained attention; which enhances convective heat transfer by introducing swirl into the main flow and disrupting the boundary layer at the tube surface through alterations in surface geometry. Twisted tape inserts are devices that demonstrate better performance in laminar flow compared to turbulent flow. Conversely, other passive techniques like ribs, conical nozzles, and conical rings are generally more effective in turbulent flow than laminar flow. A recent research trend is the utilization of nanofluids in combination with other passive heat transfer enhancement techniques like turbulators, ribs, and twisted tape inserts in heat exchangers, which can reduce exergy losses and improve overall convective heat transfer coefficient and effectiveness of heat exchanger.
