Abstract

The model of acoustic measuring channel and new algorithms for calculation of flow velocity and propagation velocity of acoustical signals in flows are proposed. These algorithms enables one to use the ultrasound pulse measuring method for describing gas flow velocity and propagation velocity of acoustic signals in the gas and liquid flows. It enables to apply the ultrasound pulse measuring method for investigation dynamic processes in the gas and liquid flows as well as for obtaining qualitatively new information about physical changes in such flows. The results of experimental investigation of the gas flow velocity and flow acceleration are submitted too.
