baal New Member Li bin Join Date: Jun 2009 Posts: 3 Rep Power: 16	The zero-lift drag includes Cf(viscous) and Cf(Pressure).When the Re number increased, the Cf(viscous) decrease, and the Cf(Pressure) increased slightly, do the phenomenon reasonable? The base pressure increased when Re increased? Could you tell me some papers about it? thanks a lot.
