Modeling of nanomaterial transportation within an enclosure with imposing external magnetic source

With involving the magnetic wire near the inner wall, FHD effect has been examined in this research to augment the free convection of ferrofluid inside the container. The tank filled with water containing iron oxide (with volume fraction of 0.04). Such concentration of ferrofluid allows using single phase formulation-based empirical data. The variable magnetic strength within the tank creates Kelvin force. CVFEM approach was incorporated to solve the equations which have been simplified with defining the stream function. The impact of Kelvin force (Mn-F), buoyancy (Ra) and fraction of ferrofluid (phi) have been examined in results. Kelvin force as well as buoyancy force makes the temperature of inner wall to decrease about 28.5%. Impose of variable magnetic makes main eddy to convert into two eddies. Upper eddy rotates clockwise while the bottom smaller eddy rotates in reverse direction. The position of bottom eddy in near the wire. With growth of Mn-F and Ra, Nu increases about 80.81% and 64.6%. Augment of phi leads to augmentation of Nu about 33.71%.

Automated summary

This research investigates the enhancement of free convection of ferrofluid inside a container by involving a magnetic wire near the inner wall. The study finds that Kelvin force and buoyancy force cause a decrease in the temperature of the inner wall, and variable magnetic strength transforms the main eddy into two eddies. Additionally, the fraction of ferrofluid also affects the phenomenon.
