Velocity and thermal slip effects on MHD nanofluid flow past a stretching cylinder with viscous dissipation and Joule heating

The motivation behind the current study is to investigate the flow and heat characteristics of magnetohydrodynamic (MHD) silver-water (Ag/H2O) nanofluid under the influence of Joule heating and viscous dissipation over a stretching cylinder in the presence of suction/injection and slip boundary conditions. Problem formulation is created considering low magnetic Reynolds number subjected to boundary layer theory. Two different models of thermal conductivity and dynamic viscosity based on unlike shapes of nanoparticles, namely spherical and cylindrical (nanotubes), are also considered. The associated PDEs related to conservation terms of hydroflow and hydrothermal are molded to system of non-dimensional ODEs with the help of appropriate similarity transformation.The obtained nonlinear equations are solved with the help of numerical approach Runge-Kutta-Fehlberg (RKF) fourth-fifth order via shooting algorithm. The convergence of its solution profiles has been demonstrated through graphs and numerical data. A detailed parametric study is performed to describe the influences of relevant physical parameters on velocity and temperature profiles. Nusselt number is also tabularized and examined for both models. Some of the results of the investigation are effects of magnetic parameter and thermal slip to decrease the velocity profiles, which in turn causes the increment in temperature profiles. Moreover, temperature fields show a similar behavior for dissipation and heat generation/absorption parameter, but the reverse trend is observed in the case of suction/blowing parameter. The computed results are validated with existing ones for limiting sense and provided excellent agreement.
