Ultrasonic systems for liquid pulverizer

Analyzing known liquid pulverizers which are driven by piezoelectric transducers we obtain that almost all of them are using longitudinal vibrating mode. So we decide to create a dual-effect system which will act as a pump and sprayer. Using FEM analysis the proposed model was analyzed and it is natural longitudinal frequency was found. Modeling results (frequency, displacement) were compared with real parameters of working transducer and they were nearly the same. The main study object was to find how fluid moves through a capillary under ultrasonic vibrations. The experimental results are populated below.
