Hey guys,
I am a new user of Floworks and I am trying to model the turbulenceof a fairing on the hull of a ferry. The ferry runs at about 10 m/s(~20 knots) and generates a thick turbulent boundary layer on theface of the fairing. In my analysis so far I have not seen thepresence of turbulent eddies that I expect, nor do I see a boundarylayer on the fairing or the hull.
For the initial conditions I specify a constant -10 m/s flow. Theinitial mesh is very fine (I suspect a boundary layer thickness ofabout 1 inch assuming Re ~10^7). For turbulence parameters I chooseturbulent only but I understand that the turbulent energy anddissipation differ in every problem, so I don't really have numbersto insert there.
My latest attempt includes specifying a boundary condition on thehull and using the flow inlet parameter to specify a 1 inchboundary layer thickness and 0 flow at the boundary. Viewing theresults afterwards still shows a constant velocity profile of-10m/s and no turbulent eddies. I worry that I am setting theproblem up wrong.
Can anyone please help?
Thanks much,
