Comparative analysis of (Zinc ferrite, Nickel Zinc ferrite) hybrid nanofluids slip flow with entropy generation

This investigation is about hybrid nanofluid flowing over a sheet. We considered two-dimensional Darcy-Forchheimer flow of different hybrid nanofluids with the influence of uniform heat source sink and nonlinear thermal radiation. Different nanoparticles can be used to improve the thermal conductivity of a liquid. A study comparing the various hybrid nanofluids to nanofluid is considered. Here, we have selected manganese Zinc ferrite and Nickel Zinc ferrite as nanoparticles with kerosene oil and engine oil as carrier liquids. Suitable similarity transformations are used to construct the required ordinary differential equations. The influence of several non-dimensional parameters on velocity and thermal gradients is analyzed through graphs. Also, entropy generation is computed and analyzed through graph for different involved parameters. Here, we observed that MnZnFe2O4-NiZnFe2O4-C10H22-C8H18 had lower velocity when compared to other two solutions. The entropy generation and Bejan number are high in MnZnFe2O4-NiZnFe2O4-C8H18 when compared to MnZnFe2O4-NiZnFe2O4-C10H22-C8H18 and MnZnFe2O4-NiZnFe2O4-C10H22 and increase in heat generation parameter increases the rate of heat transfer.

Automated summary

This study analyzes the flow of hybrid nanofluid over a sheet, investigating parameters such as velocity, thermal gradients, and entropy generation. Results show that certain hybrid nanofluids exhibit lower velocity and higher entropy generation. Increasing the heat generation parameter can enhance the rate of heat transfer.
