Abstract:
Active
ow control can be used to improve the aerodynamic e ciency of passenger
aircraft, road tra c and wind turbines amongst other applications. This work
describes the fabrication of an ultra-compact microvalve that has been designed as
part of an active aerodynamic
ow control system that generates airjets of a scale
and velocity that have been shown to have desirable e ects on the macroscopic air
ow. The design of the microvalve is based on criteria speci ed by the requirements
of active
ow control and the piezoelectric bimorph actuator which opens and closes
the valve outlet. Cont/d.
