An experimental investigation was carried out to determine the effects of gas and liquid flow rates and flow consistency index on the liquid-phase axial dispersion coefficient, pressure drop and the liquid holdup for two-phase downflow and upflow in a fixed bed. Water and non-Newtonian liquids were
Velocity profiles for unsteady laminar flows of power law non-Newtonian fluids in pipes have been derived using an explicit finite difference technique. Three unsteady flows have been considered, viz. (1) The transient start-up following the sudden imposition of a constant pressure gradient to a fl
## Abstract Twoβphase, annular flow of gases and nonβNewtonian liquids through horizontal pipes is modeled, and a prediction method for pressure drop and gas volume fraction is proposed. The prediction method consists of a modification, based upon shear rate dependence of the apparent viscosity of
