摘要

This work has been studied a comprehensive examination of segmented heating in a square enclosure packed with porous materials and Cu-Al2O3/water hybrid nanofluid with segmented magnetic field. The results are generated by using in-house code implementing the FVM, SIMPLE, TDMA algorithm and ADI sweep for the coupled transportation equations and appropriate boundary conditions. Effects of geometric variations along with parameters, namely Darcy-Rayleigh number, Darcy number, Hartmann number under different number of segmented heating and magnetization. More stress has been laid on the physical understanding of the results. In response to constant uniform heating approach of single whole wall, the work explores an important development of 246% rate augmentation with two same size heater segments positioned mid-centered on opposed walls of thermal system.
