Research on the Performance of Novel Porous Fence

摘要

A new type of porous fence called Deflector-Porous Fence (DPF), which contains deflectors with different angels, has been developed. This paper studies numerically the velocity, surface pressure and turbulence intensity distribution behind the novel wind fence using FLUENT software, while comparing its characteristics with the conventional fence. The validity of the numerical method has been evaluated by comparing the simulation results with the wind-tunnel experimental data. As a result, the numerical predictions show good agreement with the experimental results. The deflectors on the novel porous fence play a good role on guiding the bleed flow to be a parabolic motion. It also shows that the novel porous fence with smaller velocity, pressure drop and turbulence intensity has better performance than the conventional one.
