Effect of damper and heat source on wind catcher natural ventilation performance

Elmualim, A. A. (2006) Effect of damper and heat source on wind catcher natural ventilation performance. Energy and Buildings, 38 (8). pp. 939-948. ISSN 0378-7788 doi: 10.1016/j.enbuild.2005.11.004

Abstract/Summary

Experimental wind tunnel and smoke visualisation testing and CFD modelling were conducted to investigate the effect of air flow control mechanism and heat source inside rooms on wind catchers/towers performance. For this purpose, a full-scale wind catcher was connected to a test room and positioned centrally in an open boundary wind tunnel. Pressure coefficients (C-p's) around the wind catcher and air flow into the test room were established. The performance of the wind catcher depends greatly on the wind speed and direction. The incorporation of dampers and egg crate grille at ceiling level reduces and regulates the air flow rate with an average pressure loss coefficient of 0.01. The operation of the wind catcher in the presence of heat sources will potentially lower the internal temperatures in line with the external temperatures.
