September 24, 2011, 17:02	low and negative torque	#1
eng.nassim New Member nassim swlyman Join Date: Aug 2009 Posts: 11 Rep Power: 17	hi all I'm speaking about simulation of VAWT (2d) although posts in this site related to VAWT complaining of high torque , I'm facing very low torque values for some low TSR values and for high values of TSR the average torque is completely negative. Is this related to reference values in fluent ( Area, length , Depth,...) or some thing else.? what Does negative torque mean? I'm writing my master report and I'm really don't have much time?
