Abstract

This article presents a novel method of utilizing the thrust generated by synthetic jet actuators to generate torque. Piezoelectric-based synthetic jet actuators were used to create a device with two isolated cavities and orifices. Weight balance and hotwire anemometry were used to quantify the thrust generated by the synthetic jet actuator. Each orifice provides a maximum thrust of 0.15gf, thereby generating a net maximum torque of 17.17gf mm. The torque generated can be used to produce a rotary motion. Such a novel device may be useful where a high-momentum rotary jet may be employed for heat transfer and mixing enhancement.
