NUMERICAL AND EXPERIMENTAL INVESTIGATIONS OF SPEAKER-DRIVEN SYNTHETIC JET ACTUATOR FOR ELECTRONICS COOLING APPLICATIONS
Краткое описание
A synthetic jet is a preferable device to remove heat from microelectronic systems due to its low power consumption, minimal noise, and simplicity. In this study, a speaker-driven synthetic jet is investigated to analyze its cooling capability for possible use in electronic devices. Both numerical and experimental analyses are carried out on a synthetic jet oriented vertically. A three-dimensional numerical simulation of synthetic jet impingement cooling is carried out in ANSYS Fluent with dynamic mesh method. The excitation frequency and voltage to generate the synthetic jet is set to 100 Hz and 4 Vpp (voltage peak-to-peak), respectively. The effect of heater input power (3 W to 15 W) and orifice-to-plate distance (10 mm to 70 mm) are studied for a constant cavity of 8-mm orifice diameter. The simulation results are validated using experimental data, and good agreement is achieved. Results show that the studied input power does significantly affect Nuavg for 10 mm ≤ H ≤ 70 mm.
