Abstract

As cavitating flows can exhibit many unsteady length scales, the modeling of the smaller-scale features requires special attention to the turbulence modeling approach. As for many engineering applications, cavitation is associated with high Reynolds number flows, where traditional methods that reveal such features, such as large eddy simulation, are impractical due to significant increases in the computational requirements. As discussed in this paper, a more recent approach, referred to as detached-eddy simulation, enables a more efficient strategy to simulate the finer-scale dynamics with a minimal increase in the computational requirements. The implementation of such an approach is discussed, and solutions from the method display the added ability to capture a much broader spectrum of the turbulent scales, cavity dynamics, and better predict a range of cavitating flows.
