2D velocity vector profile measurement on bubbly flow using ultrasonic technique

This paper describes a measurement technique for a two-dimensional (2D) velocity vector profile in the two-phase bubbly flow. The Ultrasonic Velocity Profiler (UVP) method, which is a nonintrusive technique applicable for real-time measurement, is proposed to simultaneously obtain a 2D velocity vect...
