Unresolved pressure fluctuations at the sub-grid scale (SGS) level of large eddy simulation (LES) or Reynolds-averaged Navier–Stokes computations affect cavitation inception predictions, as SGS low pressures are simply ignored. We present a framework to take unresolved flow into account. Representing canonical turbulence, in this paper, homogeneous isotropic turbulence (HIT), fluctuations, and ...
