MHD Flow of a Hybrid Nano-Fluid in a Triangular Enclosure with Zigzags and an Elliptic Obstacle

The current study uses the multi-physics COMSOL software and the Darcy-Brinkman-Forchheimer model with a porosity of epsilon = 0.4 to conduct a numerical study on heat transfer by Cu-TiO2/EG hybrid nano-fluid inside a porous annulus between a zigzagged triangle and different cylinders and under the influence of an inclined magnetic field. The effect of numerous factors is detailed, including Rayleigh number (103 <= Ra <= 106), Hartmann number (0 <= Ha <= 100), volume percent of the nano-fluid (0.02 <= phi <= 0.08), and the rotating speed of the cylinder (-4000 <= w <= 4000). Except for the Hartmann number, which decelerates the flow rate, each of these parameters has a positive impact on the thermal transmission rate.

Automated summary

This study numerically investigates the heat transfer of Cu-TiO2/EG hybrid nano-fluid inside a porous annulus using the multi-physics COMSOL software and the Darcy-Brinkman-Forchheimer model. The results show that, except for the Hartmann number which decelerates the flow rate, all other parameters have a positive impact on the thermal transmission rate.
