Query: Partially-Averaged Navier-Stokes Simulations of Turbulence Within a
  High-Order Flux Reconstruction Framework   High-order methods and hybrid turbulence models have independently shown
promise as means of decreasing the computational cost of scale-resolving
simulations. The objective of this work is to develop the combination of these
methods and analyze the effects of high-order discretizations on hybrid
turbulence models, particularly with respect the optimal model parameters and
the relative accuracy benefits compared to approaches such as under-resolved
direct numerical simulation (URDNS). We employ the Partially-Averaged
Navier-Stokes (PANS) approach using the flux reconstruction scheme on the flow
around a periodic hill and the wake flow of a circular cylinder at a Reynolds
number of 3900, the latter of which we provide direct numerical simulation
results and novel statistical analysis. By increasing the order of the
discretization while fixing the total degrees of freedom, it was observed that
larger improvements in the prediction of the statistics and flow physics were
generally seen with PANS than URDNS. Furthermore, less sensitivity to the
resolution-control parameter was observed with a high-order discretization,
indicating that high-order discretizations may be an effective approach for
increasing the accuracy and reliability of hybrid turbulence models for
scale-resolving simulations without a significant increase in computational
effort.
