Abstract
Abstract This research investigateswindcatcher usage in Mosul for ventilation . The choice of a squareshape windcatcher diagonally partitioned along its height attached to a room of dimensions 4x6x4 m. Indoorair motion speed and movement were studied to assess a windcatcher’s performance .A computational model is used with Autodesk Simulation CFD software for the simulation case. Part of this study was dedicated to find the geometrical characteristics of the windcatcherparameters: - height (4 cases), cross-section (3 cases) and location with respect to the room (4 cases).Another part is to analyze a yearly weather data of Mosul to find the prevailing speed and direction for all cases (a range of 20-30oC is chosen as a thermal comfort temperature range) and to use them as an input forthe simulation to find the best case of the windcatcher. The results shows that the best heights of 4m , the best cross-section of 1x1 m and the best location of the wind catcher isfound to be at the middle of long side of the room. The weather data shows that the prevailing wind speedbetween 1.62 to 4.83 m/s. The final result of the study confirm that the direction of the windcatcher and the room which can give the best performance using all the above selected parameters in Mosul is 337 oNNW.
