3D CFD modeling of air flow through a porous fence

Abstract

Numerical simulation has played an important role in systematic study on the performance of porous fences over the last three decades. In this paper, a 3D CFD model to simulate air flow through a porous fence is presented. The simulated velocity data has been tested against experimental data acquired in wind tunnel experiments under the same conditions. Good agreement has been observed between the numerical and the experimental results within the fence effective zone, demonstrating that the 3D CFD model presented in the paper is generally sound and can be used to systematically assess the performance of porous fences. It is the first step to create a CogInfocom channel through which a numerical system (CFD) has communicated with a natural cognitive system (prototype and physical experimental system), in a way that improves human cognitive abilities to comprehend air flow through porous fences.
