Dr. Sighard F. Hoerner (born 18 April 1906, Münster, Germany — d. 22 June 1971, Brick Town, USA) was an important figure in the aerodynamics field and is known worldwide for his two compendiums of aerodynamic knowledge, Fluid-Dynamic Drag and Fluid-Dynamic Lift. He is also notable for his design work on the pioneering STOL aircraft, the Fieseler Fi 156 Storch. In fluid dynamics, the drag coefficient (commonly denoted as: , or ) is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment, such as air or water. It is used in the drag equation in which a lower drag coefficient indicates the object will have less aerodynamic or hydrodynamic drag. The drag coefficient is always associated with a particula… flea baths for puppiesNettet31. mai 2015 · As it can be seen, the drag coefficient can be considered mesh independent with a number of cells equals to 650 000. The difference with the finest grid result is less than 1%.
