Review of the Effects of Stationary/Rotating Cylinder in a Cavity on the Convection Heat Transfer in Porous Media with/without Nanofluid

Abstract

The mixed convective heat transfer has many multiple engineering applications, such as solar collectors, electronic equipment cooling and heat exchanger, and geothermal engineering. This work presents comprehensive coverage of a wide range of published studies in terms of convection heat transfer inside the enclosure in recent years. The convective heat transfer in porous media with/without nanofluid, and the effect of stationary/rotating cylinder inside cavities, as well as the position of the cylinder, had been addressed and discuss to draw the main conclusions and recommendations. It is worthy to mention that the mixed convective with the effect of entropy generation with inner bodies in enclosure has been investigated less than the other simple enclosure shapes due to its complexity. The researchers can be extended their future studies by adding the MHD effects with mixed conviction in simple/complex shapes of enclosure. This study gives an important and useful summary for provides researchers of heat transfer in academic and industrial. At the end of this investigation, the governing equations of the 2-D mixed convection in an enclosure filled with porous medium, and nanofluid addressed.

The Baffle Length Effects on the Natural Convection in Nanofluid-Filled Square Enclosure with Sinusoidal Temperature

“…Natural convection can be used for nuclear reactor cooling and thermal conditioning. It can be used to cool nuclear reactors, regulate the temperature of electronic equipment, and cool buildings and solar panels, in addition to various agricultural applications [ 2 , 3 , 4 , 5 ]. Natural convection has been extensively studied in air-filled enclosures with differently heated vertical walls, with different boundary conditions for the heat source walls and different boundary conditions of other walls.…”

Magnetoconvection around an elliptic cylinder placed in a lid‐driven square enclosure subjected to internal heat generation or absorption

“…Some of the previous works done on mixed convective heat transfer are captured in various studies. [1][2][3][4][5][6] Olayemi et al 7 considered lid-driven convective flow in a square cavity exposed to different modes of heating and submitted that the maximum heat transfer took place close to the lower wall and the highest value of flow velocity occurrence at y = 0.4 in the vertical midplane at x = 0.5. Khan et al 8 analyzed lid-driven convective flow in a trapezoidal configuration housing a cylinder that was subjected to rotary motion.…”
