Mixed Convection Magnetohydrodynamics of Different Forms of Triangular Cavity Involving CuO/Water Nanofluid

Abstract

The current research studied the two-dimensional mixed heat transfer in three different cavities with inlet/outlet opening, The heat source is located on a part of the bottom wall, Several parameters such as (10 ≤ Re ≤ 150); (0.1 ≤ Ri ≤ 10); (0 ≤ Ha ≤ 100); (0.02 ≤ φ ≤ 0.08). Were analysed on three different models. The results showed a difference in the presence of the magnetic field, we notice an increase in the value of the Reynolds number leads to a decrease in the velocity of heat flow. The heat transfer value increases in the second cavity to give a maximum value, while it is low in the first and third cavity. Additionally, improvement of Nuavg at the second cavity of the right wall, which is folded inward. The latter is characterized by a low Nuavg compared to the first and second. The improvement in Ha and φ improves the convective heat transfer. In addition, with increasing concentration of the nanofluids, the average number of Nusselt in the three cavities increased. It is hoped that these results will be useful in optimizing convection, these results are consistent with literature published literature.
