Influence of an effective Prandtl number model on squeezed flow of γAl2O3-H2O and γAl2O3-C2H6O2 nanofluids

- The effective Prandtl model for the thermal conductivity of nanofluids is considered.
- Squeezed flow is formulated using the said model.
- Water and Ethylene Glycol have been considered as the base fluids while γAl2O3 as the nanoparticles.
- Numerical as well as analytical results are presented.

The flow squeezed between parallel flat plates that placed horizontally in nonporous media is of great interest because of its uses in many industries and engineering side as well. In the light of this fact, we have considered the flow of nanofluids between two plates. The dimensional flow is successfully reduced into a set of self-similar form with the help of feasible similarity variables. In the next step, the system is solved analytically (Homotopy Analysis method) and to ensure the analytical computation, numerical solutions (by means of Runge-Kutta method) are also performed. Influences of the effective Prandtl number are investigated on thermal filed and local rate of heat transfer along with ingrained physical quantities. Under certain assumptions, present results are compared with already existing ones in the literature and found to be agree well. The major outcomes of the presented letter are described in the last section.
