Boundary layer noise Kinetic energy dissipation Air bubble layer Maximum stable bubble size bubble noise spectra between the noise spectra of a layer of air bubbles in a turbulent flow and' a maximum stable bubble size which can exist in the same flow. An air bubbie layer with individual bubble sizes greater than a maximum stable size was introduced into the boundary layer of water flowing along a smooth flat plate. It was found that the maximum stable bubble size was related to the turbulent kinetic energy dissipation as had been previously shown by other investigators ; Office of Naval Research Arlington, Virginia 22217 1981-09-31T21:42:52Z 1981 Report 14 http://purl.umn.edu/109914 http://purl.umn.edu/109914 en_US Project Reports 202 http://purl.umn.edu/109914 2 eng
