Convective non-conducting magnetic fluid flow and heat transfer due to the rotating cone in the presence of magnetic dipole

Ferrofluid flow in a rotating system is useful due to its potential applications in spin coating, effective electrical motors and rotating shaft sealing. This work investigates the flow and heat transfer of a non-conducting magnetic fluid due to the uniform rotation of a cone under the influence of a magnetic dipole. The finite element approach is used to numerically solve the nonlinear coupled differential equations. Comparison of the current numerical model with prior numerical results is also shown by discarding some physical characteristics of the current model. Increasing the buoyancy force and thermomechanical interaction increases circumferential velocity while decreasing tangential and normal velocity, whereas increasing the Prandtl number increases circumferential velocity while decreasing temperature. The dominance of buoyancy force increases tangential and circumferential friction on the cone surface as well as the heat transfer rate.
