The current work describes the 2 dimensional hybrid nanofluid (HNF) flow of incompressible wall jet with mass transpiration, heat transfer and radiation effect, where the jet streamwise velocity varies in a power-law. On applying the appropriate similarity transformations to these equations, a system of nonlinear ordinary differential equation (ODEs) was obtained. Then, this resulted system was numerically solved using MATLAB bvp4c solver and the results of velocity profiles and temperature distributions were demonstrated in the graphical form. Further, analytical investigating for the flow equation was introduced with distinguishing of three cases for suction, impermeable and injection as relation of the power-law. It was found that increase in the volume fraction of nanoparticles inclines the velocity profile in suction. Further, the temperature distribution shrinks with the increase in suction and injection parameter. •The solution of hybrid nanofluid flow and heat transfer with thermal radiation was discussed.•The similarity transformations were adapted.•This resulted system was numerically solved using MATLAB.•The increase in thermal radiation results in the increased thermal boundary thickness.•The industrial processes can decide the operating temperature.
