Turbulent Flow in a Square Duct using LES -- CFD Online Discussion Forums

February 7, 2009, 21:25	Turbulent Flow in a Square Duct using LES	#1
Hock Ming Guest Posts: n/a	Hi, I'm using LES solver to simulate a transient turbulent flow in a square duct using pressure gradient. However, after more than 200,000 time steps(time step size of 0.0001), I still can't get any mean secondary flow at the corner region of the duct. Has anybody done the same simulation and achieve the desired mean secondary flow?
