Effect of thermal radiation on engine oil nanofluid flow over a permeable wedge under convective heating: Keller box method

摘要

Purpose - The purpose of this paper is to examine the magneto hydrodynamic flow and heat transfer of nanofluids over a permeable wedge based on engine oil which is under the effects of thermal radiation and convective heating. Design/methodology/approach - The equations governing the flow are transformed into differential equations by applying similarity transformations. Keller box method is used to bring out the numerical solution. Findings - The discovery interprets that temperature as well as the velocity of Ag-engine oil nanofluids are more noticeable than Cu-engine oil nanofluids. Thermal boundary layer increases for radiation parameter as well as Biot number. Fluctuations of co-efficient of drag skin friction as well heat transfer rate at the wall are also tested. Originality/value - Till now, no numerical studies are reported on the heat transfer enhancement of the permeable wedge under thermal radiation on engine oil nanofluid flow by considering convective heating.
