Numerical Simulation of Non-normal Wind Load on Porous Fences

A Numerical Study on Flow around Nonuniform Porous Fences

The effects of a porous fence with a nonuniform porosity on flow fields are investigated numerically. First, an experiment with a non-uniform porous fence located in a wind tunnel is performed to obtain a reference data set. Then, a numerical model that utilizes the finite volume schemewith a weakly compressible-flowmethod to solve the continuity and momentum equations is developed. The numeric...

Numerical Simulation of Dynamic Wind Load of the Foot-bridge

Pedestrian bridge structures are usually sensitive to the effects of wind due to their relatively high slimness and low weight. The arising forces can excite both oscillation in the direction of the wind and also crosswise torsion-flexure oscillation which can result in a local or (in the case of coupled torsion-flexure oscillation) complete loss of aerodynamic stability of the structure. This ...

Numerical Simulation of Combustion with Porous Medium in I.C. Engine

Porous media has interesting features in compared with free flame combustion due to the extended of the lean flammability limits and lower emissions. Advanced new generation of internal combustion (IC) engines are expected to have far better emissions levels both gaseous and particulate matter, at the same time having far lower fuel consumption on a wide range of operating condition. These c...

Absolute Permeability Calculation by Direct Numerical Simulation in Porous Media

Simulating fluid flow at micro level is an ongoing problem. Simplified macroscopic flow models like Darcy’s law is unable to estimate fluid dynamic properties of porous media. The digital sample reconstruction by high resolution X-ray computed tomography scanning and fluid-dynamics simulation, together with the increasing power of super-computers, allow to carry out pore-scale simulations throu...
