Heat transfer analysis of micropolar hybrid nanofluid over an oscillating vertical plate and Newtonian heating.

The unsteady flow of micropolar hybrid nanofluids through an oscillating vertical plate having infinite length has been analyzed in this study. This flow goes through Newtonian heating and thermal radiation. To enrich the thermal properties, we add copper and alumina nanoparticles to micropolar fluid. For the enhancement of heat transfer, water is taken as base liquid. The dimensionless reduced form of the governing equations for velocity, temperature and microrotation is formed by using dimensional analysis. We used Laplace transform method to have the exact solutions of these governing equations. MathCad's software has been used to visualize the effects on the flow of fluid graphically. We found that microrotation, velocity and temperature are inversely proportional to Prandtl number but directly proportional to Grashof number. Further, temperature can be enhanced for increasing value of Newtonian heating, radiation and volume fraction of nanoparticles copper and alumina. [ABSTRACT FROM AUTHOR]
