Cool. How sensitive is the Strouhal number to viscosity at Re = 100 indirectly via the shedding frequency? My hunch is not very and so the implicit diffusion from coarsening is not having a first order effect. See Implicit Large Eddy Simulation (ILES) as the reason I ask. How bad is the Strouhal error under coarsening of a less fancy method? Beware, my computational fluids is meh these days. |
