Heat Transfer Enhancement Using Ferro-Nanofluid with Magnetic Field in Tube Having Inserted Twisted Tube

Abstract

This study investigates heat transfer enhancement through the application of ferronanofluid in conjunction with twisted tape inserts, with particular emphasis on the effect of escalating ferro-nanofluid concentration. The influence of a magnetic field on the ferro-nanofluid and its subsequent impact on heat transfer rates is also simulated. To gain a deeper understanding of the stream field, computational fluid dynamics studies are undertaken, with the Cartesian direction being the focal point of mathematical methodologies. The numerical model and mesh are constructed using ANSYS. The numerical results elucidate the heat transfer improvement process utilizing twisted tape and ferro-nanofluid under various conditions: rotational cycles, magnetic field intensity, and ferro-nanofluid concentration. Moreover, the influence of these conditions on pressure, temperature, and fluid velocity is assessed when deploying ferro-nanofluid in conjunction with a magnetic field for heat transfer enhancement. The findings reveal that, irrespective of the operating conditions, fluid pressure tends to decrease while the fluid temperature and velocity increase with the intensification of the magnetic field, the concentration of ferro-nanofluid, and the rotational cycles.
