Abstract: A numerical investigation of laminar flow in a two-dimensional, Cartesian flow that exits from a short channel with a backward-facing step is carried out in this work for the Reynolds number range of 0.00054 < Re < 540. We studied the steady state fluid dynamic, phase change and heat transfer of the flow. The domain of the simulation is extended beyond of the outlet of the channel to take account the casting or jet velocity of fluid. The governing equations for a Newtonian incompressible fluid were solved with the finite element method. We analyzed the flow behavior occurring for different outflow velocities and three different configuration of the step. The incompressible working fluid was glass. The temperature, streamline, phase change and pressure fields are obtained and analyzed as a function of the position. In order to obtain a better understanding of the step angle influence on the fluid dynamic, we obtained the heat transfer flux rates and the axial veloci!
ty profiles. For low outflow velocities, the flow of the fluid along the wall domain is laminar but there is phase change from liquid to solid of the fluid at the step region, the temperature fields show hot glass at the entrance with cooling of the fluid through the domain, being this behaviour independent of the step configuration, however the size of the phase transition zone depends on the step inclination. For high outflow velocities there are vortices formation at the step region of the channel, however the temperature of the glass remains constant and the phase of the fluid is liquid for the different step configuration studied.
