Characterization of a Commercial Synthetic Jet Actuator for Air Quality Applications

Abstract

In this study, a commercial electromagnetic synthetic jet actuator (SJA) was characterized to determine its flow patterns and sphere of influence within a room. Its axisymmetry was also evaluated. The objective of this research is to explore the potential application of this commercial SJA for indoor air quality (IAQ) control and its limitations for such application. A small fan of similar size was also partially characterized. Results showed that the SJA is axisymmetric, and it uses a small power input to impact the airflow over 1 m from the jet exit. Further, while the SJA showed less flow output than the fan in this study, it had significantly greater dynamic pressure per unit power. This feature could be potentially useful for indoor air quality control applications.
