Abstract
Mounted on the body of a fan blade is a micro-electro mechanical system which includes at least one thin silicon film forming an integrated circuit, and an actuator connected to the circuit for generating vibrations. If used as a noise-killing system, the actuator generates vibrations which offset (reduce) unstable air flows along the blade body. If used in a heat exchanger to improve the heat exchange effect, the system generates vibrations which amplify the unstable air flow, e.g., to amplify turbulence and vortexes.
