Abstract

This article examines the non-aligned stagnation point flow and heat transfer of an Ethylene-Glycol and water based Nano fluid towards a stretching surface utilizing hematite (Fe3O4) as a heat enhancing agent. Resulting differential equations of the physical problem are solved numerically using Mid-point integration as a basic scheme along with Richardson extrapolation as an enhancement scheme. Influence of the flow governing parameters on the dimensionless velocity and temperature profile are expressed through graphs. Skin frictions co-efficient and Nusselt numbers are tabulated. It is observed that Ethylene-based nano fluids have higher local heat flux than water-based nano fluids. Computed numerical results of skin friction co-efficient are in good agreement with the existing available literature for the limited case.
