Abstract
The article investigated the transportation of water-based nano-ferro-fluid using MHD (magnetohydrodynamics) channel. Water with cobalt ferrite magnetic material (ferro particles) (CoFe2O4−H2O) is utilised for studying the flow field, induced magnetic field, and temperature field in the presence of heat flux. Authors have utilised ‘MATHEMATICA NDSolve command’, to solve non-dimensional governing ODEs with predetermined wall and free stream conditions. Authurs have utilised key physical parameters of model to characterise the results. Graphs display the impacts of these parameters on the flow field, temperature, velocity, and magnetic stream function gradient of the ferrofluid suspension. The physical model generates numerical solutions for temperature, velocity, and induced magnetic field. When fluid is heated, the velocity in the channel increases, resulting in enhanced heat transmission near the upper wall as well as reduce at bottom wall. In addition, the parameter Q for heat source/sink effect has the tendency to decrease the temperature profile when Q<<0 and increase it when Q>>0. Utilising ferrofluid in a channel to enhance heat transfer, control flow, or for medicinal reasons, among others, relies on the specific application and desired outcome.
