Blasius friction

WebIt is widely accepted that the Blasius friction relationship gives the best representa-tion of friction factor data of available formulations for Re D <100×103. For higher Reynolds numbers, the friction factor relationship is often based on a logarithmic scaling of the mean velocity profile. In the most general form, it is assumed that U+ = 1 κ WebOct 13, 2012 · The friction force that is obtained by the integrating of friction stresses is expressed in a dimensionless form by introducing the friction factor. The expression for the Darcy-Weisbach friction factor has the form of a power law of the IR whose power value is called the Blasius exponent which depends on the spatial occupancy index (SOI).
