as shown in Figure 16.33a. However, larger secondary ow entrainment is created
during the suction phase of the synthetic jet as shown in Figure 16.33b. The uid
that is sucked in during the suction phase will be pushed out during the next ejec-
tion phase [17].
Mahalingam et al. [17] reported the airow and thermal properties of a syn-
thetic jet ejector. Figure 16.34 shows the airow rate created by a synthetic jet
ejector through a channel as a function of the channel width. It is seen that the
airow rate increases monotonically although it tends to an asymptotic level for
channel widths larger than
