Impact of magnetic field on nanofluid thermophysical treatment within enclosure

Numerical technique for examining the transport of nanofluid within the porous container has been applied. The tank has one curved hot wall which is located in the center of the outer cylinder. The single-phase approach to deriving properties of nanofluid was applied and Darcy law has been implemented to involve the porous term in the equation. The format of the equation has been converted to stream function format to remove the pressure terms and final equations were solved via CVFEM. The written code was verified according to the previous data of the published work. Outputs showed that loading alumina causes Nu to augment by 26.71% when Ha is zero and it can be increased about 41.22% when Ha = 15. Applying a magnetic field can reduce the Nu around 37.93% when Ra=700. With increase of strength of rotating cell with the rise of Ra, Nu increases by about 38.22%. Changing the shape of alumina can increase the Nu by about 11.73% when Ha=15 and Ra=700.

Automated summary

A numerical technique was employed to study the transport of nanofluid within a porous container, using a single-phase approach and implementing Darcy law to involve the porous term in the equation. The equation format was converted to stream function format and solved using CVFEM.
