The boundary layer flow problem for non‐Newtonian hybrid nanofluid over moving wedge is discussed. The hybrid nanofluid is synthesized by equal suspensions of MWCNTs and SiO 2 nanoparticles in a binary mixture of EG–water. The physical problem is modeled through continuity, momentum, and energy equations and a two‐parameter rheological model relates shear stress to shear rate is used that obey the trend of experimental result. The relevant governing equations are simplified form by means of the similarity transformation and then solved by an analytical scheme. The results are obtained at different nanoparticles volume fractions for velocity and temperature profiles and displaced graphically for discussion. In addition, displacement and momentum thicknesses are calculated numerically to understand the deflation in mass flow rate and momentum flux to due to boundary layer growth. The results show that velocity profile is reduced due to increasing of viscosity by nanoparticle volume fraction. In this consequence, the displacement and momentum thicknesses are increased.
