Abstract

The present work is concerned with the application of the PANS-\(\zeta \)-f (Partially-Averaged Navier-Stokes) variable resolution model by Basara et al. (AIAA J 49:2627–2636, 2011), formulated in conjunction with the universal wall treatment, to the process of generation and destruction of a tumbling vortex in a square-piston compression machine (investigated experimentally by Borée et al. Phys Fluids 14:2543–2556, 2002) and the swirling flow in a tube generated by two tangential inlets with the outlet geometry resembling an orifice with an eccentrically positioned opening (reference experiment is by Grundmann et al. Int J Heat Fluid Flow 37:51–63, 2012). In addition, the complementary RANS computations (by using the \(\zeta -\textit{f}\) model of Hanjalic et al. Int. J. Heat Fluid Flow 25:1047–1051, 2004), representing also the background RANS formulation in the present PANS model) and LES (in conjunction with the Standard Smagorinsky subgrid-scale model) of both configurations are performed. The PANS-\(\zeta \)-f model description and its preliminary validation by simulating a fully-developed channel flow and a separating flow over a series of axisymmetric hill-shaped constrictions are given in a companion article by Chang et al. (5th International Symposium on Hybrid RANS-LES Methods, 2014)
