Non-Newtonian behavior of an electrical and magnetizable phase change material in a filled enclosure in the presence of a non-uniform magnetic field

This work aims to study the non-Newtonian behavior of a magneto- and ferro-hydrodynamic phase change material (PCM) inside a differentially heated enclosure. The enclosure is occupied with a Power-law non-Newtonian PCM, and a non-uniform magnetic field is imposed on the adjacent hot wall. The left a...

Description
Summary:This work aims to study the non-Newtonian behavior of a magneto- and ferro-hydrodynamic phase change material (PCM) inside a differentially heated enclosure. The enclosure is occupied with a Power-law non-Newtonian PCM, and a non-uniform magnetic field is imposed on the adjacent hot wall. The left and right of the enclosure are subjected to the high and cold temperatures, and the top and bottom of the enclosure are insulated. A deformed mesh technique along with the Stephan condition is applied to track the interface of the solid and molten regions. The impacts of the alterable parameters including the Rayleigh number (104
