Ультразвукове канальне вимірювання температури та швидкості потоку повітря

Abstract

This work is devoted to the ultrasonic probe application in measuring a temperature and velocity of air flows inside channels. The pulse and continuous probe techniques are considered. The final expressions are received for the needed parameters estimation. The temperature is defined by a time delay necessary for a probing pulse to cover the doubled distance between channel walls. Definition of the air flow velocity is based on the Doppler frequency shift of the received oscillations.
