BARBOSA-SALDANA, Juan G; JIMENEZ-BERNAL, José A; GUTIERREZ-TORRES, Claudia del C  y  MORENO-PACHECO, Luis A. Numerical Analysis for a Mixed Convective Flow Over a Tri-Dimensional Horizontal Backward-Facing Step. Inf. tecnol. [online]. 2007, vol.18, n.6, pp.3-12. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642007000600002.

Laminar mixed convection over a backward-facing step is studied and presented in this work. A finite volume discretization technique is used to solve the momentum and energy equations. The SIMPLE algorithm is used to link the pressure distribution and velocity field inside the computational domain.  The buoyancy forces affecting the velocity and temperature distributions are simulated for constant air flow and constant Reynold number (Re=200) for a mixed convective flow (Ri=3) and the results are compared with those of pure force convective flow (Ri=0). The results indicate that the re-circulation zones at the vicinity of the back step are reduced if the buoyancy effects are considered. It is concluded that the flow is highly tridimensional.

Palabras clave : numerical simulation; mixed convection; forced convection; SIMPLE algorithm.
