A Combined Packed-Bed Friction Factor Equation: Extension to Higher Reynolds Number with Wall Effects


Correspondence concerning this article should be addressed to W. C. Hecker at hecker@byu.edu.


A unique combination of classic packed bed friction factor equations and newly refit correlation constants is proposed which produces a new friction factor correlation which significantly improves predictions in high turbulence regimes, high porosity regimes, and high wall effect regimes.
