網頁occur at high Reynolds numbers (typically Re > 103), is a situation in which inertial forces are muchlarger than vis-cous forces. It is characterized by a rich and complicated flow structure ofinteracting vortices. Bycarefully avoiding any instabilities, however atRe 網頁2024年5月15日 · The cell Reynolds number together with the Peclet number is used to determine what physics dominants a cell (advection vs diffusion) and therefore what discretization scheme should be employed. For upwind schemes you want this number to be high, not low. For DNS, you want this number to be <1 everywhere. May 16, 2024, …

Recall the definition of the Reynolds number: Where ρ is the density, v is the velocity, μ is the viscosity of air and l is the characteristic length. The characteristic length is typically the chord length of an airfoil but can also mean the overall length of the airframe. When we scale down a model, we are decreasing l.
網頁2011年12月28日 · In my opinion, the cell Reynolds number defined in COMSOL is based on velocity increment (delta_u or relative velocity) in each cell while not the absolute velocity used in the common definition of Reynolds number. The velocity increment (delta_u) is much smaller than the absolute velocity. 網頁2024年5月31日 · For increasing Reynolds number the maximum grows until the flow in the honeycomb cell reaches the transition region, after which it starts to decrease. For R e ≤ 2670 the turbulence intensity immediately downstream of the honeycomb is around I = 0.01. for R e > 2670 the turbulence intensity significantly increases with the Reynolds number.
