August 13, 2022, 15:54	Drag Force Calculation	#1
Pratik More New Member Pratik More Join Date: Aug 2022 Posts: 2 Rep Power: 0	Hii i am trying to find the drag force on savonius turbine using 2d transient system. As the turbine is rotating constantly and the projected area is changing what should I put in reference values of area?

sjsivabharathy New Member jawahar sivabharathy Join Date: Jan 2011 Posts: 12 Rep Power: 15	Hi Pratik, The drag force acting on the turbine changes with rotation. If you are using varying projected area you can't compare the coefficient with time. I would suggest you to use planform area to non-dimensionalize the drag force for understanding the dynamics. Thanks. HHOS likes this.
