Replies: 22 Horizontal Axis Wind Turbine Views: 5,481 Posted By CFD XUE yes, tip speed ratio is 6. I think boundary... yes, tip speed ratio is 6. I think boundary layer is more stable in turbulent flow as compared to laminar flow. So, separation is smaller in Turbulent flow as compared to laminar flow. Since...

Calculated torque by using laminar simulation is 64 N-m while 35 N-m by using k-epsilon turbulence model. Both are...
