Abstract
Involving curved walls and imposing magnetic source were main techniques of present study to augment the convective flow. Sinusoidal inner wall and circular outer wall experience uniform flux and cold temperature. The base fluid mixed with iron oxide then it can be more affect by FHD. To produce Kelvin force, wire with electric current was install near the inner wall. To obtain the amount of scalars in whole domain, new modeling approach was selected and procedure was verified based on previous numerical work. Concentrations of ferrofluid, strength of Kelvin and gravity forces are main variables of current work. With involve of nano-powders, the conductivity enhances and convective rate elevates about 12.44%. Both buoyancy and Kelvin forces help the nanomaterial to move easier inside the container. Nu augments about 93.04% and 35.43% with elevate of Mn-F at Ra = 1e3 and 1e4. Besides, grow of Ra deals with increment of Nu around 43.55% and 0.71% at Mn-F = 0 and 4000.
