ON THE COMBINATION OF AIR VELOCITY AND FLOW MEASUREMENTS IN SINGLE-SIDED NATURAL VENTILATION CONFIGURATIONS

Single sided natural ventilation configurations are very frequent espe cially in buildings in urban environments. Four single sided ventilati on experiments were carried out in a full scale outdoor Test Cell faci lity. Air velocity measurements were taken at various heights in the m iddle of the opening. The average air flow rate through the opening wa s derived using the tracer gas decay technique. This work presents the results of an investigation into the relationship between the air vel ocity at the opening and the bulk air flow rate measurements. The pape r presents a description of the experimental set-up as well as a quali tative discussion of the results.
