Mixed Convective Flow of Micropolar Nanofluid across a Horizontal Cylinder in Saturated Porous Medium

Abstract

The micropolar nanofluids are the potential liquids that enhance the thermophysical features and ability of heat transportation instead of base liquids. Alumina and Titania nanoparticles are mixed in a micropolar fluid. The impact of convective boundary condition is also examined with assisting and opposing flows of both nanofluids. The main objective of this study is to investigate mixed convective flow and heat transfer of micropolar nanofluids across a cylinder in a saturated porous medium. Non-similar variables are used to make the governing equations dimensionless. The local similar and non-similar solutions are obtained by using the Runge-Kutta-Fehlberg method of seventh order. The impacts of various embedded variables on the flow and heat transfer of micropolar nanofluids are investigated and interpreted graphically. It is demonstrated that the skin friction and heat transfer rates depend on solid volume fraction of nanoparticles, Biot number, mixed convection, and material parameters.

Sinusoidal Natural Convective Flow of Non-Newtonian Nanoliquid Over a Radiative Vertical Plate in a Saturated Porous Medium

“…Latest advancements in nanotechnology manifested a novel epoch of study known as micropolar nanoliquids. Rashad et al [27] appended Titania and Alumina and nanoparticles in a micro-liquid to analyze the influence of aiding and opposing flows of both nanliquids in a porous medium. Tabassum et al [28] studied an investigation overall study on microrotation nanoliquid under the impact of viscosity difference.…”

Time-dependent three-dimensional Oldroyd-B nanofluid flow due to bidirectional movement of surface with zero mass flux

“…Some recent studies can be found in the literature. [23][24][25][26][27][28] Multiple efforts have been presented and demonstrated to identify the behaviors of distinct Newtonian and non-Newtonian materials under various assumptions and geometries. For example, Wang 29 first considered the three-dimensional flow due to stretching sheet.…”
