ACOUSTIC WAVE TESTING DEVICE FOR SHALLOW WATER FLOW

摘要

An acoustic wave testing device for a shallow water flow comprises: a reactor (1) provided with a testing chamber (2), wherein a side surface of the reactor extending in a length direction is capable of applying a confining pressure to the testing chamber (2); an acoustic wave testing component provided within the testing chamber (2) and comprising a transmission member (3) and a receiving member (4), wherein a line connecting the transmission member (3) and the receiving member is perpendicular to the length direction; a temperature and pressure testing component (5) provided within the testing chamber (2); a pushing force component (6) provided at an end of the reactor (1) extending in the length direction, at least a portion of the pushing force component (6) extending into the testing chamber (2); a liquid injection component (7) communicated with the testing chamber (2); and a control portion (8) electrically connected to the transmission member (3), the receiving member (4), the temperature and pressure testing component (5), the pushing force component (6), and the liquid injection component (7), and used to acquire acoustic wave information transmitted by the transmission member (3), acoustic wave information received by the receiving member (4), and pressure and temperature information acquired by the temperature and pressure testing component (5). The acoustic wave testing device for a shallow water flow is capable of testing acoustic responses of a shallow water flow under different pressure changes, and facilitates studying an impact pattern of the shallow water flow on acoustic features.
