Abstract:

Description of the operation of a blow-down-type, low-noise water tunnel developed for measuring turbulent boundary layer TBL noise on large-diameter sonar transducers is presented. Some of the tunnel characteristics given include mean velocity profile and TBL noise measurements on 116 in., 38 in., and 5 in. D transducers. TBL noise measured on 116 in. and 38 in. D transducers compares well with the noise measurements carried out by other investigators. Author
