Free Convection in a Caterpillar Shaped Triangular Enclosure Filled with Different Nanofluids

Abstract

A numerical work is conducted for the free convection in a right triangular cavity filled with water-based nanofluids. The bottom wall is in a caterpillar wavy shape which is assumed as a hot wall whereas the rest walls of the enclosure are considered as a cold wall. Governing equations of the problem are discretized through the finite volume method. The present study is undertaken to appraise the effect of the constrained parameters i.e. various types of nanofluids (TiO2, CuO, and Al2O3), volume fractions of thenanoparticles and Rayleigh number (Ra=10 5 -10 7 ). The higher augmentation in the rate of heat transfer is observed for the Al2O3-water-based nanofluid for each Rayleigh number.

Mathematical Modelling of MHD Natural Convection in a Linearly Heated Porous Cavity

“…Alam et al [13] analyzed the convection heat transfer, which occurs due to the heated base of the cavity, filled with nanofluids and obstacles present in the center of the cavity subjected to the applied magnetic field effect. Triveni and Panua [14] appraised the heat transfer generated by nanofluids such as Al2O3, TiO2, CuO -H2O due to the effect of natural convection on the caterpillar-shaped enclosure. Chaabane and Jemni [15] studied the MHD natural convection on linearly heated cavities.…”
