Abstract
We propose a partially-averaged Navier-Stokes equations (PANS) closure to predict the Taylor-Green vortex (TGV) flow. The results confirm the ability of the model to efficiently predict this problem. Yet, the physical resolution of the model should guarantee that only phenomena amenable to modeling are represented by the closure. This requires resolving the vortex-reconnection process of the TGV flow.
