Computational investigation of non-uniform magnetic field on thermal characteristic of nanofluid stream inside 180° elbow pipe

The thermal efficiency of the heat exchanger is substantial in chemical and mechanical systems. The presence of the non-homogeny magnetic field considerably enhances the heat rate of nanofluid stream. In this exploration, the presence of the non-uniform magnetic intensity on the heat rate of nanofluid stream is noted inside the 180 degrees elbow pipe. FVM is used to model the flow characteristics and temperature distribution through the 180 degrees elbow pipe. Our major focus is to demonstrate the main influences of the non-uniform FHD on flow stream and heat transfer of nanofluid in various inlet velocities and magnetic intensities. Achieved outcomes display that growing the magnetic intensity from 1e + 6 to 4e + 6 enhances the average Nusselt number about 30%. Our findings show that increasing the inlet velocity to Re = 100 decreases the magnetic effects about 17% on the heat transfer growth.

Automated summary

The efficiency of heat transfer in heat exchangers in chemical and mechanical systems is significantly influenced by the presence of a non-uniform magnetic field. Increasing magnetic intensity enhances the Nusselt number, while increasing inlet velocity reduces the impact of magnetic effects on heat transfer.
