Numerical investigation of wind effects on the perforated structures

Popis výsledku v původním jazyce

The paper deals with a numerical analysis of wind effects on structures with perforated surfaces. The solution based on FEM model is governed by the stabilized Navier-Stokes equations for incompressible fluid. Special attention is given to perforated screens. Such a partly resistance barrier always introduces considerable numerical difficulties resulting from the complexity of a flow distortion when the fluid is passing through. For simplification, the barrier is assumed as a thin screen with specific resistance parameters where the fluid flow mechanism needs not be resolved. The general influence of a screen on the flow field is a loss in the normal momentum component and the change in flow direction. On the other hand, to simulate the fluid mechanicsauthentically it requires to specify the relevant input parameters that can be determined by an experiment or by using a corresponding handbook.
