Abstract:
Flow models taking into account pipe roughness are presented. Beta functions are described for some types of roughness. The modeling results are compared with data of classical experiments.
Keywords:
wall layer, dynamic length, height and curvature radius of roughness elements, the first and second limiting regimes.
