nasir.iitd is on a distinguished road
Hi everybody,
I'm running LES in Ansys 15.0 fluent for studying turbulence of rotating pipe flow.Inlet condition is such that rotating pipe flow leads to solid body rotation.Domain is a circular pipe. While plotting RMS profile of y-velocity(tangential), it is showing negative values. How is it possible? RMS negative??
Can anybody help to get rid-off this problem?
