Main features of the present analysis is to investigate the magnetohydrodynamic (MHD) nonlinear mixed convection flow of Carreau nanofluid. Flow is due to stretching sheet with thermal and solutal convective conditions. Intention in present analysis is to develop a model for nanomaterial. The nonlinear ordinary differential systems are obtained. Homotopy algorithm leads to solutions development. Velocity, temperature, nanoparticles concentration, surface drag force and heat and mass transfer

Temperature field and heat transfer rate are similar observation for thermal Biot numbers. Moreover qualitative behaviors of nanoparticles concentration and mass transfer rate are reverse for larger Brownian motion. thermal radiation; convective conditions. in an asymmetric channel. Hayat et al. [5] analyzed the aspects of heat transfer in flow of Carreau fluid towards a stretched sheet. Hayat et al. [6] studied nonlinear convective flow of Carreau nanofluid in the presence of Brownian motion and thermophoresis aspects. Hsiao [7] inspected MHD stagnation point flow of a Carreau nanoliquid towards a stretching surface. Features of Newtonian heating and MHD flow of Carreau liquid presented by Hayat et al. [8]. MHD flow of Carreau nanofluid with mass flux condition is investigated by Khan et al. [9]. Khan et al. [10] studied the radiative flow of Carreau nanofluid with heat generation/absorption. The features of nonlinear thermal radiation in boundary layer flow is significant due to its application in industrial and engineering fields such as, furnace design, glass production, polymer processing, gas cooled nuclear reactors and also in space technology like aerodynamics rockets, propulsion system, missiles, power plants for inter planetary flights and space crafts which works at high temperatures. Consequently, thermal radiation effects cannot be ignored in such processes. The radiative heat flux in the energy equation is described through Rosseland relation. Cortell [11] examined the features of nonlinear radiative flow of viscous fluid in the
