Abstract
In this study, the thermal and fluid flow characteristics of a piezoelectric fan are experimentally evaluated by altering its height and distance from single-fin and plate-fin heat sinks. Based on the thermal resistance of heat sinks, the piezoelectric fan performance is assessed. Particle image velocimetry is used to study the flow velocity field generated by the piezoelectric fan.
