Development of an instantaneous velocity-vector-profile method using conventional ultrasonic transducers

Autor: Tomonori Ihara, Hyun Jin Park, Dongik Yoon

Publikováno v: Measurement Science and Technology. 33:035301

A velocity vector profile technique based on an ultrasound pulsed Doppler method can enrich the information on the flow field. However, it has shown low availability because a new design of special transducers is required for each measurement case. T
