Correlation of residual velocity with throw and terminal velocity from a louver-faced unidirectional diffuser.

Author(s) : YOUSOUFIAN H. H.

Summary

The central thesis of the paper is the stated importance of predicting the residual air velocity in the microenvironment of an occupant served by a ceiling-mounted air diffuser obtaining horizontal airflow along the ceiling. Experimental data are presented for a unidirectional, louver-faced, ceiling-mounted diffuser supplying air to a room under isothermal test conditions. Test data correlating residual air velocity with terminal air velocity are given for five different arrangements of furnishings in the zone of occupancy that correspond to typical conditions encountered in practice.
