Simulation of ferrofluid behavior under the efficacy of magnetic field through a porous complex container

Numerical code based on steam function formulation for scrutinizing the nanomaterial flow and heat transfer within the porous container with sinusoidal hot surface has been developed in this study. The model involves the impression of Lorentz force and buoyancy force has the main role in movement of nanomaterial. Shape of nano -powders and their concentrations have been selected as two other factors. The validation test has been done according to the previous paper which means that present code has good accommodation. In presence of Ha, the Nu declines about 26.5 %. Augmenting Ra in absence of Ha, makes Nu to increase about 28.64 %. When Ha = 0 and 15, loading nanoparticles makes the Nu enhance about 28.18 % and 42.82 %. Augmenting m causes the Nu to increase around 11.94 % and outputs showed that loading nanoparticles has greater impact in presence of magnetic field.

Automated summary

A numerical code based on steam function formulation has been developed to study the flow and heat transfer of nanomaterials within a porous container with a sinusoidal hot surface. The model considers the influence of Lorentz force and buoyancy force on nanomaterial movement, with the shape of nano-powders and their concentrations as additional factors. Validation tests show that the code has good accuracy. Results indicate a decrease of 26.5% in Nu with the presence of Ha, and an increase of 28.64% in Nu with an increase in Ra in the absence of Ha. Loading nanoparticles leads to a 28.18% and 42.82% increase in Nu for Ha = 0 and 15, respectively. An increase in m causes an 11.94% increase in Nu, and the results show that loading nanoparticles have a greater impact in the presence of a magnetic field.
