Effects of Thermal Radiation and Ohmic Heating on hydromagnetic Maxwell Hybrid Nanofluid Flow

The constitutive model for the Maxwell fluid is mostly used in the polymeric industry to model the flow of viscoelastic fluids. Since 2005, fluids properties have been enhanced by the emergence of nanofluids and hybrid nanofluids. Studies on Maxwell hybrid nanofluid have been carried out under different conditions, but the effects of both thermal radiation and ohmic heating on the hydromagnetic Maxwell hybrid nanofluid flow has not been investigated. Motivated by this, this study probes into the role that thermal radiation and ohmic heating plays on a 2-D incompressible hydromagnetic flow of Maxwell hybrid nanofluid; a suspension of both Alumina/Copper nanoparticles in a Maxwell fluid. The model of the is formulated then transformed into a non-dimensional system using similarity variables. The shooting technique is employed to convert the dimensionless equations to their equivalent initial value problem; which is then solved using MATLAB bvp4c solver. Parametric analysis shows: Grashof number (1→7) increases velocity 35%, decreases temperature 28%; magnetic parameter (1→7) raises temperature 60%, reduces velocity 71%; nanoparticle fraction (1%→4%) elevates temperature 22%, lowers velocity 18%; radiation parameter enhances heat transfer 31%; Weissenberg number reduces boundary layer 42%.
