Abstract Contribute of nanoparticle shapes on MHD nanofluid flow of water, ethylene glycol and engine oil based Cu, Al 2 O 3 and SWCNTs over a stretched surface in the presence of thermal radiation has been investigated. The three classic models of nanoparticle shapes are registered into report, i.e. sphere (m = 3.0), cylinder (m = 6.3698) and lamina (m = 16.1576). The controlling partial differential equations (PDEs) are regenerated into ordinary differential equations (ODEs) by manipulating irrefutable accordance conversion and it is proposed numerically by executing Runge Kutta Fehlberg method with shooting technique. It is recognized that the lamina shape ( m  = 16.1576) SWCNTs in the SWCNTs-engine oil shows a powerful impact on temperature distribution with increase of nanoparticle volume fraction. Nanoparticle shapes have an enlightened outcome on particle transport and heat transfer. The shape of the nanoparticles, particularly the lamina SWCNTs – engine oil with combined effect of thermal radiation in the presence of magnetic field is encountered an important role on cosmical, geophysical fluid dynamics; also in solar physics, involved in the sunspot development, solar cycle and medicine research.
