Turbulent Friction Factor for Two-Phase: Air-Powerlaw Fluid Flows Through Horizontal Tubes
Keyword(s):
Turbulent experimental friction factors for air and power-law fluid flows through a horizontal tube are reported. The power-law fluids studied were aqueous solutions of Carbopol® (at concentrations 1000 and 2000 wppm). The two-phase friction factors were correlated in terms of the generalized Reynolds number (Re*). Over a range of the Re* from 6000 to 80,000, the simpler homogeneous model is accurate enough for engineering prediction of turbulent friction factor for air and power-law fluid flows through straight tubes.
