Abstract

AbstractThe squeezed MHD flow of water, ethylene glycol and engine oil based metallic nanoparticles over a sensor surface in the presence of thermal radiation energy have been investigated. The physical significance of the problem is water, ethylene glycol and engine oil based on the geometry and the interaction of copper (Cu), alumina (Al2O3) and carbon nanotubes (SWCNTs and MWCNTs). The governing partial differential equations of momentum and energy are transformed to similarity equations (ODEs) for certain families of the controlling parameters. The numerical and analytical solutions of the resulting ODEs are solved using fourth or fifth order Fehlberg method with shooting technique and optimal homotopy asymptotic method (OHAM) and it is also found that there is no significance difference between them. It is investigated that in squeezing flow phenomena, SWCNTs-engine oil in the presence of thermal radiation energy gives approximately more than 30% enhancement in the heat transfer as compared to the water based SWCNTs and MWCNTs
