Abstract

In this paper, dynamic behaviors of different chamber neck designs are studied. Within a micro-nozzle channel, different chamber neck designs for controlling bubble growth are used, including conventional structural chamber neck as well as virtual chamber neck. Dynamics of bubble growth rates under different input signals and chamber neck configurations are measured using a high speed microscopic imaging system. The experimental results show that with the help of virtual chamber neck at upstream, the bubble interface will move faster toward the nozzle direction, which will enhance the actuation force of the liquid toward the nozzle direction.
