Web29 jun. 2005 · For low Mach number turbulence, Lighthill has given a result which expresses the acoustic radiation of turbulent fluid in terms of a fourth‐rank velocity correlation. Through the use of the Navier‐Stokes equation this relation can be put in terms of the space‐time pressure correlation. For very large Reynolds number turbulence (in the … WebThis paper compares frequency domain and time domain predictions from the ShipMo3D ship motion library with observed motions from model tests and sea trials.
