Application65 Acoustic Analysis of Flow Sensor in the Pipe

An analysis model is an ultrasonic sensor to detect the object flowing in the pipe. Time history is obtained for how the sound waves propagate when five sine waves are input.

A sensor is attached to the pipe. 2D analysis is performed.
The sine waves are entered at the inlet. The sound pressure at the outlet is analyzed.
The result shows how the sound waves propagate.
