Abstract
Synthetic jet actuators (SJAs) are devices that control fluid flow by synthesizing surrounding fluid without altering the flow from the cavity. Before optimization, the selected diaphragm frequencies are subjected to a CFD solution using a dynamic mesh. Output parameters of selected loudspeaker-driven SJA are optimized under quiescent conditions. Comparisons are made between the best optimization candidate design point, experimental reference, and baseline CFD study before optimization. Re increases by 17% at 50[Formula: see text]Hz and 8.7% at other frequencies. St decreases by almost 30% across all frequencies. [Formula: see text] is maximized and held over 4. Optimized design, based on response surface model, demonstrated a consistent ability to produce higher, more centralized velocity profiles.
