Abstract:

Methods are described for obtaining similarity-law characterization for arbitrary roughnesses indirectly from pipe-flow head loss, flat-plate drag, and rotating-disk torque. The roughness characterizations are used to make viscous drag predictions by means of boundary-layer calculations. A simplified drag prediction method using form factors and equivalent rough flat plates is described in detail. Author
