Abstract

A steady two-dimensional conjugate heat transfer with Ohmic dissipation mixed convection of an incompressible Maxwell fluid on a stagnation point has been studied. The whole system is an extrusion forming process. The governing equations have been solved by similarity transformation method and finite-difference method. The above two methods have been used to analyze present problem which is a different way to analysis the similar problems. The numerical solutions of the flow velocity distributions, temperature profiles, the wall unknown values f′′(0) and θ′(0) for calculating the heat transfer of the similar boundary layer flow had been carried out as function of the viscoelastic number, Prandtl number, buoyancy parameters, etc. The effects of those parameters have been discussed in detail. The results have been shown that it should produce greater heat transfer effect with larger values of free convection parameter, Prandtl number and conduction–convection number. On the other hand, the magnetic parameter or Eckert number will reduce the heat transfer effect.
