Treatment of ferrofluid through a sinusoidal cavity with impose of magnetic source

In the current article, to decline the temperature of heat element, enclosure with the wavy wall has been utilized with incorporating magnetic source. The wire near the inner surface generates the space-dependent Kelvin force. Adding nano-sized powder into H 2 O creates a new fluid which has a higher capability to absorb heat. Defining vorticity term creates the simpler format of equations and CVFEM was utilized for simulation. To test the correctness of code, the previous published article was considered and a low amount of error percentages illustrates the nice accuracy. The space-dependent Kelvin force affects the nanomaterial and increase the convective flow and strength of eddy increase. As nano-sized material added, Nu enhances around 12.79% owing to augmentation of conductivity. When Mn F = 2000 and zero, augment of Ra makes the Nu to augment around 1.04% and 47.94%. When Ra = 1e4, augment of Kelvin force causes Nu to grow around 35. 36%.
