Abstract
An assembly is provided for determining a parametric design of a large eddy breakup device in which the assembly comprises a water tunnel turbulent pipe flow section; a large eddy breakup device ring disposed within the pipe flow section; and a wall pressure sensor array operable to detect wall pressure in the turbulent pipe flow section. Energy in a wavenumber frequency spectra of wall pressure fluctuations is redistributed via changes to the parametric design in order to minimize turbulent wall pressure fluctuations with the result of reduced flow noise and drag.
