“…The vibrator is the main component of the jet, that through vibration produces the movement of the fluid from the energy entering the actuator [20]. The vibrator can be a piezoelectric part [21], a piston [22] or a resonant device such as a loudspeaker [23]. However, in this study, the jet cavity is not designed, and instead, the SJs are modelled as a time-dependent inlet/outlet velocity boundary condition, alternating between suction and injection processes.…”

“…An experimental setup was arranged by Lyu et al [110] to study the thermal performance of piston-driven synthetic jet impingement (see Figure 11). The range of operational frequencies used was from 5 Hz to 25 Hz, and the jet-target spacing (H/d) ranged from 2 to 14.…”

Jet impingement is considered to be an effective technique to enhance the heat transfer rate, and it finds many applications in the scientific and industrial horizons. The objective of this paper is to summarize heat transfer enhancement through different jet impingement methods and provide a platform for identifying the scope for future work. This study reviews various experimental and numerical studies of jet impingement methods for thermal-hydraulic improvement of heat transfer surfaces. The jet impingement methods considered in the present work include shapes of the target surface, the jet/nozzle–target surface distance, extended jet holes, nanofluids, and the use of phase change materials (PCMs). The present work also includes both single-jet and multiple-jet impingement studies for different industrial applications.
