In order to improve convective flow, this study primarily used techniques including curved surfaces and a strong magnetic force. The main pillars of current research are gravity forces, ferrofluid concentrations, and Kelvin force. Additionally, the use of nanopowders increases conduction features and facilitates the movement of nanofluid.
In order to improve convective flow, this study primarily used techniques including curved surfaces and a strong magnetic force. Cold temperatures and even flow are experienced by both the circular outer wall and the sinusoidal inner wall. FHD can have a bigger effect when combined with iron oxide in the base fluid. The electric current-carrying wire was positioned close to the interior wall in order to produce Kelvin force. A novel modeling approach was chosen to ascertain the number of scalars throughout the entire domain, and the process was validated using earlier numerical work. Gravity forces, ferrofluid concentrations, and the Kelvin force serve as the main pillars of current research. Conduction features increase and the Nu rises by 12.44% when nanopowders are used. Due to gravity and magnetic forces, the nanofluid can move more easily through the container. At Ra=1e3 and 1e4, respectively, Nu increases by 93.04% and 35.43%; with an increase in Mn-F. Additionally, Nu rises with Ra at Mn-F=0 and Mn-F=4000 by 43.55% and 0.71%, respectively.
