Figure 4

Vertical velocity component for a total gas flow of a) 250sccm and b) 2000sccm as a function of the vertical position for both plasma-on ("on") and plasma-off ("off") conditions.

Figure 3

Streamline representation of the time-averaged flow field for a) the deactivated array and b) the operating array for an applied gas flow rate of 250sccm.

Figure 6

emporal evolution of the vertical velocity component spatially averaged in the gas domain directly above the cavities as a function of operating time and external gas flow rate.
