Abstract

The purpose of this article is to inspect the impact of singular magnetic source on the thermal efficiency of a ferrofluid containing Fe304 nanoparticles flowing through an elbow pipe with a junction. The study utilizes comprehensive numerical simulations to analyze the flow stream and temperature distribution, with a particular focus on the role of the generated vortex in enhancing heat transfer along the elbow pipe. The simulations are conducted using computational fluid dynamics techniques to model the flow of the ferrofluid. The thermal analysis considers various magnetic intensities and velocities of the ferrofluid. The obtained data reveals that the vortex created via singular magnetic source contributes to a rise in the average heat transfer along the elbow pipe. Additionally, the study finds that the magnetic intensity plays a more significant role when the inlet velocity of the ferrofluid is lower. Specifically, a 300% increase in the magnetic field results in an approximately 17% improvement in the thermal performance. Overall, this research sheds light on the importance of a non-uniform singular magnetic source in enhancing thermal efficiency in ferrofluids flowing through elbow pipes. The findings highlight the potential for optimizing heat transfer in such systems by controlling magnetic intensity and fluid velocity.
