Description

The effect of inlet configuration on room air movement was investigated in a full-scale model in a comprehensive experiment. Room flow patterns were identified by zones and boundaries on an air flow plan. Velocities in the zone were correlated well with the inlet parameters as long as air flows in the full rotary flow zone on the plan. Regression equations, obtained through dimensional analysis and from the measurements at 41 inlet conditions, showed that the mean and turbulent fluctuations of flow velocity were nearly proportional to the incoming air speed at the slot inlet and to the opening raised to the 0.6 power. Good correlations were also found between the velocity in the occupied region and the inlet jet momentum number.
