ESDU 12006
Method to determine surface finish required to minimise local skin friction in the presence of a turbulent boundary layer.
Abstract:
ESDU 12006 uses the Nikuradse criterion, with compressibility corrections, to determine the limiting surface roughness for an aerodynamically smooth surface in the presence of a turbulent boundary layer. The accompanying program gives the option of basing the calculation on local skin-friction coefficient and flow conditions (determined, for example, by using the VGK or VFP programs, published in the ESDU Transonic Aerodynamics Series). Options are also provided for calculations on an equivalent flat-plate with forced or free transition. Comparison is made with current wind-tunnel practice but the method is also applicable to full-scale aircraft configurationsIndexed under:
