    Anuar Ishak
    This paper concerns with the boundary layer flow and heat transfer over a permeable stretching/shrinking sheet in a viscous fluid, with the bottom surface of the plate is heated by convection from a hot fluid. The partial differential equations governing the flow and heat transfer are converted into ordinary differential equations using a similarity transformation, before being solved numerically. The effects of the suction, convection and stretching/shrinking parameters on the skin friction coefficient and the local Nusselt number are examined and graphically illustrated. Dual solutions are found to exist for a certain range of the suction and stretching/shrinking parameters. The numerical results also show that suction widens the range of the stretching/shrinking parameter for which the solution exists.

    This research investigatesthe problem of stagnation point flow and heat transfer over a stretching/shrinking sheet past a porous medium with suction effect. Firstly, the mathematical model that governed the fluid flow and heat transfer were formulated. Then, the governing nonlinear partial differential equations were transformed into ordinary differential equations using similarity transformation. The system of ordinary differential equations is then solved numerically using bvp4cfunction in Matlab software. The effect of suction on the skin friction coefficient and the local Nusselt number,as well as the velocity and temperature profiles,are obtained and analysed. The numerical result obtained ispresented in the form of graphs and tables. The dual solutions are obtained for a certain range of parameters. The stability analysis has been performed and the result showsthat the upper branch solution is stable while thelower branch solution is unstable
