Momentum transfer for multi-solid-particle power-law fluid systems at high Reynolds numbers

Abstract

Using a concentric-spheres free surface model and a fourth order polynomial Karman-Pohlhausen method, the dimensionless tangential stress, the pressure distribution, the viscous, form and total drag coefficients and the void functions were numerically computed for a solid sphere in a swarm in power-law fluids at high Reynolds numbers. The friction factor for a packed bed calculated from the total drag coefficient of a solid sphere in a swarm in power-law fluids agreed with an extrapolation of the experimental data.
