Outlines a semi-empirical method for calculating the velocity and temperature fields in air-conditioned auditoriums. The method takes account of the interaction between the various jets in the auditorium, the boundaries of the auditorium and the exhaust flow by adding the momentum flux of all jets at each point and later correcting the velocity fields for deviations from the equation of continuity. Similarly, the temperature field is calculated so that the heat balance equation is preserved. The effect of the walls is calculated by the mirror method. The results of the calculations are shown to be in good agreement with measurements in scaled models. Discusses several examples of design based on this procedure.
KEYWORDS: Calculating, auditoria, air flow, models, comparing, accuracy, air distribution.
