Abstract The objective of this experimental flow visualization study was to assess the ability of synthetic jets to be adapted for control of airflows and particulates in an indoor environment. Specifically, flow visualization was used to determine whether small synthetic jet modules installed onto the surface of a supply diffuser could significantly impact the angle at which supply air left the diffuser when mixing into the room air. A synthetic jets module was installed in a lab with a high air exchange rate (7 ACH) to test this methodology. This lab space is representative of occupational indoor environments that may require ventilation strategies beyond typical systems to ensure the safest and most efficient operation of the space. Three synthetic-jet modules were tested including two pairs of small one-inch diameter jets used in a previous small-scale ventilation study and two larger two-inch diameter jet pairs constructed specifically for this study. Statistical methods were used to compare the visualized supply flow with active synthetic jet flow control versus a baseline case (no flow control). Results showed a significant impact on the angle of mixing of the supply air.
