Experimental set-up and measurement procedures were carried out to evaluate the performance of a windcatcher, using an open working section wind tunnel. Then CFD simulations were made to be compared with experimental results.The performance of the windcatcher depends on the wind speed. The wind direction also has importance
This paper reports some findings from IEA ECBCS Annex 35 about wind driven flow through building openings. Wind tunnel studies have been performed on simplified buildings, in order to know if pressure distributions on sealed buildings can be used to predict airflow through facade openings. A new parameter, the catchment area, is introduced by author.
MCA is a partner in a research group which is being funded by the European Commissions JOULE program to explore the application of passive downdraught evaporative cooling (PDEC) in non-domestic buildings (I). As part of MCA's task to design a full scale experimental building, special components were designed to catch the wind and distribute through the building spaces. To determine the most efficient form for these components, a series of wind tunnel tests was undertaken at the University of Ancona, Italy.
