| The steady magnetohydrodynamics (MHD) axisymmetric flow of nanofluid and heat transfer past a horizontal stretching cylinder embedded in porous medium in presence of velocity slip has been investigated. In this study, aluminium oxide nanoparticles are dropped in base fluid: water to make nanofluid. Applications of similarity transformations convert the partial differential equations corresponding to the momentum and heat equations into highly non-linear ordinary differential equations. Numerical solutions are obtained using the shooting technique with Runge-Kutta method. The influence magnetic field, porous medium, curvature parameter, slip and nanofluid volume fraction on velocity and temperature are analysed in detail. The results show that an increase in the slip parameter leads to an augmentation in the fluid flow away from the wall and also in heat transfer characteristics. When the volume fraction of nanoparticles increases and the slip increases, the heat transfer rate declines, but the heat transfer is enhanced when the curvature parameter rises. This work brings valuable perceptions on the behaviour of nanofluids which have wider engineering applications particularly in heat transfer improvement and flow control around cylindrical surfaces. | ||
