Abstract: In this study, a steady flow of micropolar hybrid nanofluid over Riga channel has been analyzed. Exponentially stretching and slip effects are also considered in this analysis. The systems of governing partial differential equations are transformed into a system of non dimensional ordinary differential equations by applying the suitable similaritytransformation. The dimensionless form of the ordinary differential equations is elucidated through numerical technique via bvp4c method. The effects of the governing parameters which involve in ordinary differential equations are highlighted through graphs while skin friction, couple stress and Nusselt numbers are highlighted through Tables. Our interest of study is to be analyzed about the heat transfer rate of micropolar hybrid nanofluid over a Riga channel. For the values of Res1∕2Cf, Res1∕2Nus and Res1∕2Cm, the week concentration gains higher values as compared to the strong concentration. The momentum boundary layer thickness decrease when the values of the modified Harman number ω to be increase while the opposite seen to be noted for the micropolar profile decreases. The values of Res1∕2Cf and Res1∕2Cm enhances for increasing in the values of ωwhile decline the values of Res1∕2Nus. The comparison with the existence literature has been worked and it is revealed to be good agreement.
