Experimental and Numerical Determination of Wind Pressure Distribution on an Object with Atypical Form

Abstract:

This paper deals with solution of air flowing around the object - atypical cross section. Result is an important parameter of pressure coefficient on the structure, what is necessary for design of buildings and structures in terms of wind load calculations. Wind tunnel measurements of wind flow and wind pressures distribution around part of the circle were performed in BLWT STU in Bratislava for 24 wind directions and different wind speeds. Measurements were performed using pressure scanner DSA 3217 (Scanivalve) and have shown significant differences between peaks of suction due to wind direction. These results were used for comparison with CFD calculations of flow around the section. This comparison of known pressure coefficient for atypical shape of cross section is the first step for testing other shapes, which are not described in Eurocode.
