Experimental determination of the performance of a four-way diffuser with variable area.

Author(s) : KENYON A. E., KIRKPATRICK A. T.

Summary

The paper examines how effectively a room air diffuser with a variable outlet area can produce a constant throw with varying flow rate. The diffuser for this study is a four-way diffuser with hinged surfaces providing a variable outlet area on two of its sides. The throws were measured downstream of one of the two fixed area outlets. Throw measurements for five fixed outlet areas were used to determine the outlet area variation with flow rate necessary for constant throw performance.
