초록정보

The characteristics of the fluid flow in a backward-facing step channel with a porous body was studied using a numerical method based on the modified SIMPLER algorithm. The momentum equations and boundary conditions were phrased in terms of the primitive variables, velocity and pressure. The Darcy's modelling term was included in the momentum equations for the porous body. The porous body was regarded as an assemblage of vertical cylinders. The study was undertaken for $0.6 \le γ \le 0.9$, $0.1 \le \mbox{Hp/H} \le 0.5$ and Reynolds number up to 300, where γ is the porosity and Hp/H the height ratio of the porous. The characteristics of the velocity and pressure in the step channel with a porous body were discussed, and also it was investigated how the recirculation region of the step channel is affected by a porous body. Through the investigation, it was disclosed that the presence of a porous body makes a considerable change in the flow field and even causes another flow seperation after the porous body.
