Numerical study of momentum and heat transfer of MHD Carreau nanofluid over an exponentially stretched plate with internal heat source/sink and radiation

In this article, the magnetohydrodynamic (MHD) thermal boundary layer of a Carreau flow of Cu–water nanofluids over an exponentially permeable stretching thin plate is investigated numerically. Internal heat source/sink is also taken into account. After gaining the system of leading equations, the appropriate transformations have been first employed to come across the fitting parallel conversions to alter the central governing equations into a suit of ODEs and then the renovated system of ODE along with appropriate boundary conditions is numerically solved by the shooting method with fourth-order Runge–Kutta technique. The consequences of the relevant factors of physical parameters on velocity and temperature of merging water (H₂O) and nanoparticles (Cu) have been exemplified through graphs.
