Abstract
A system for measuring a rising velocity and a deformation of a bubble in a viscous fluid includes a sample cell configured to hold a viscous fluid, a variable-diameter syringe provided at a bottom of the sample cell and configured to generate a bubble in the viscous fluid, two ultrasonic transmitting and receiving transducers arranged at different heights of the sample cell and configured to transmit first ultrasonic signals to the viscous fluid and receive second ultrasonic signals reflected by the bubble, and a host computer configured to analyze time-domain information of the second ultrasonic signals received by the two ultrasonic transmitting and receiving transducers, calculate the rising velocity of the bubble, build a mathematical model about a bubble size and a reflected sound pressure, analyze frequency-domain information of the second ultrasonic signals received by the two ultrasonic transmitting and receiving transducers, and calculate the deformation of the bubble.
