Bubble removal by electric and acoustic actuation for heat transfer enhancement

This paper presents a technology for the removal of bubbles using two mechanisms electric and acoustic actuation. In this study, dielectrowetting was used to separate from surface substrate, while actuation transfer eliminate separated by acoustically exciting them. addition, electrical signals various voltages frequencies were applied patterned electrodes fabricated through standard microfabrication processes in order investigate dynamic behaviors driven bubbles, such as contact angles their distances surface. Furthermore, high-speed camera measure velocities single excitation at identify velocity efficiency which transported removed excitation. To test feasibility removing multiple volumes, an experiment carried out proposed different volumes simultaneously then remove The revealed that could be all once second. method can variety industrial applications require large quantities heat.
