The squeezed MHD flow of water-based metallic nanoparticles over a porous sensor surface in the presence of a heat source has been investigated. The physical significance of the problem is the interaction and the geometry of water-based copper (Cu), alumina (Al2O3) and SWCNTs. The governing partial differential equations of momentum and energy were converted into ODEs for assured groups of the controlling parameters. The numerical and analytical solutions of the ODEs were obtained using the fourth or the fifth order Fehlberg method with shooting technique and OHAM and were analyzed. It was found that there was no appreciable difference between them. It was established that, in squeezing flow phenomena, the effect of nanoparticle volume fraction on the (SWCNTs – water) nanofluid in the presence of magnetic field with thermal radiation energy played a dominant role on heat transfer as compared to the other mixtures in the flow regime.
