Possible Redundancy in Comments of the Tutorial: channel395DFSEM
Hi,
Please consider: tutorials/incompressible/pimpleFoam/LES/channel395DFSEM
Therein, 0/U has the following comment for nu:
// Re = 395, L = pi, utau = 1, nu = pi/395 = 7.9534e-3 Yet in constant/transportProperties another comment for nu states:
// Re_tau = u_tau L / nu
// Re_tau = 395
// L = half channel height = 1
// Ubulk/u_tau = 17.55
// U_bulk = 17.55 -> u_tau = 1
// -> nu = 1*1/395 = 2.532e-3AFAIK, the second comment reflects the generally accepted value of the half channel height for this particular plane channel flow although its value can be anything. Considering the computation uses the value of nu = 2.532e-3, I believe that discarding the first comment may be useful.
Kind regards
