The National Center for Physical Acoustics, where our Ultrasonics Laboratory is located, celebrated its 30th anniversay on Friday October 14. To celebrate this remarkable milestone, an open house was held at NCPA with tours of the lab and acoustic demos. The Ultrasonics group put on two demos, the flame tube and the acoustic fountain.
Here, Cecille Labuda demonstrates standing waves on a flame tube.
Ukesh Koju demonstrates the acoustic fountain using a high intensity focused ultrasound transducer.
