Abilities of porous materials for energy saving in advanced thermal systems

Using nanoparticles in solar collector to enhance solar-assisted hot process stream usefulness

“…Solar collectors, like heat exchanger, trap solar energy and then turn it into thermal energy. The working fluid can be water, ethylene glycol or even nanofluid [47][48][49][50][51]. Various nanoparticles have been used in this field [52][53][54][55].…”

Electro‐magneto‐hydrodynamic Eyring‐Powell fluid flow through micro‐parallel plates with heat transfer and non‐Darcian effects

“…Nonlinear coupling exists between the specified differential Equations ( 13) and (24) and their relevant boundary conditions (14) and (26). To find the solutions to these differential equations, we employed an analytic method.…”

“…11,12 In addition, it can be used in hydrogen storage systems, shale reservoirs, membrane-based water desalination for reverse osmosis, and electro-kinetic energy conversion equipment. Many researchers have investigated the heat transfer process through a saturated porous medium using the Darcy model, 13,14 which is based on the assumption that seepage velocity is proportional to the pressure gradient. It is worth noting that this approach is only useful in cases where fluid motion is slow, and the permeability medium is low.…”

Experimental investigations of thermal solutions to increase heat transfer rate by utilizing the effects of pitch ratio and length

“…As the VG length increases, so does the intensity of the transverse vortex 32 . However, if the duration exceeds a specific threshold, the transverse vortices will react with one another, thereby weakening the power 33 . Three lengths are chosen based on the diameter to provide a suitable VG length.…”
