Abstract This investigation is addressed to examine the comparative consequence of thermal radiation and heat generation/absorption in steady three-dimensional MHD (Magneto-hydrodynamics) stagnation point flow of (MWCNTs + Cu /engine oil) hybrid nanofluid over a porous circular cylinder. Flow via thermal slip effect is inspected. Also, the impact of both homogeneous/heterogeneous (h–h) chemical reactions are considered for explanation of mass transportation characteristics. Here, a kind of hybrid nanofluid including MWCNTs (multi wall carbon nanotubes) and Cu (Coper) nanoparticles with engine oil as base fluid is used. Appropriate transformation procedure is implemented for renovating model expression of continuity, momentum, energy, mass transportation and boundary conditions into a set of ODEs. HAM (Homotopy Analysis Method) methodology is then employed to solve these nonlinear coupled ODEs. Furthermore, the influence of inserting model factors on velocities, temperature fields, C f (skin friction coefficient) and Nu (Nusselt number) has been investigated numerically and graphically. The core outcome specifies that hybrid nanofluid (MWCNTs + C u + engine oil) improve thermal conductivity when equated with nanofluid (MWCNTs + engine oil).
