Fluid Structure Coupling Analysis of Ultrasonic Traveling Wave Driving

Abstract:

An ultrasonic travelling wave micro-fluid driving model was presented. Principle of the driving model was introduced and finite element model was developed. Resonance frequencies were predicted by modal analysis. Fluid structure coupling analysis was done to observe the transient fluid velocity. The time-averaged velocity was calculated. Influences of driving voltage, driving frequency and fluid viscosity on time-averaged velocity were taken into accounted. The results indicate that the time-averaged velocity profile is asymmetric parabola and is influenced by the driving frequency obviously. The maximum time-averaged velocity decreases with the increasing of fluid viscosity and reflux appears when the fluid viscosity reaches to 0.07Pa·s.
