Hoerner aerodynamic drag

NettetTheoretical and experimental data on the flow through nozzles can be found in engineering handbooks. (b) The Borda-Carnot loss of pressure can be found in the literature on diffusers. (c) Drag coefficients can be found in handbooks, such as Hoerner, "Aerodynamic Drag," 1951. NettetDrag coefficients(CD) in aerodynamics are drag forces normalized with a reference area, usually the frontal area, another projection area or the wetted area. Sometimes the reference area is not given, so the drag coefficient is a misleading figure. The actual values of the CD of particular devices are confidential by nature.

When the drag is dominated by viscous drag, we say the body is streamlined, and when it is dominated by pressure drag, we say the body is bluff. Whether the flow is viscous-drag dominated or pressure-drag dominated depends entirely on the shape of the body. thunderball results wed 17th august 2022
