non-aligned ethylene-glycol 30% based stagnation point fluid over a stretching surface with hematite nano particles

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.
