Channel results: IDDES in the Vulcan code

The Vulcan code is developed in the Hypersonic Air Breathing Propulsion Branch at NASA Langley for RANS, LES, and hybrid LES/RANS computations. It is a finite-volume code with (in LES-mode) minimally dissipative numerics. The code is described at https://vulcan-cfd.larc.nasa.gov.
