Vertical dispersion of spherical, heavy particles in turbulent open channel flow

Two-phase flow insights into open-channel flows with suspended particles of different densities

“…Results like those in Fig. 5c are also reported by [26,52,53]. For all the flows (NS and NBS, and especially for the clear-water flow), the frequency of occurrence of upward velocity exceeds that for downward velocity.…”

Particle velocity detection and measurement in two-phase flow using combined electronic logic system and LDA technique

“…To analyze the distribution of local mean velocities of the solid particle quantitatively and to study the influence of each parameter referred above, we have to examine the variations of the dimensionless velocity profiles U + = f (y + ). (3.2) This procedure was used by Bouvard and Petkovic [31] for open channel flows, and Idrissi [27] for flows in circular pipes. It is necessary to know the friction velocity U * s and the suspension dynamic viscosity µ m .…”

Two-phase modeling of suspended sediment distribution in open channel flows

“…So far, diffusion models based on a single composite media have found the greatest acceptance for practical applications and usually fonn the basis for numerical or mathematical models of sediment-laden flow. With this approach, the transport of suspended particles in the vertical direction for 2D uniform open (1) (2) Revision received November 14, 2003. Open for discussion till September 30, 2004.…”
