In this paper, the concentration and velocity profiles of sediment water mixtures for open-channel flows are modelled numerically and validated with experimental results. A continuum approach, the drift flux model, is used. The mixture consists of volume fractions with different particle sizes. Hindered settling is taken into account with the closure relation of Richardson and Zaki. Transport equations are used for sediment transport. Turbulence is modelled with the LES (large eddy simulation) WALE model. The discretization of the transport and Navier-Stokes equations is done with the finite volume method. The Navier-Stokes equations are solved using a fractional step method. The numerical results are compared with experimental results concerning open-channel flows.

“…Not surprisingly, these works have revealed that the bulk thermal and mechanical modulii of such materials vary dramatically with particle/binder ratio. [15][16][17][18] For example, Lewis 18 observed an inverse relationship between particle/binder ratios and damping ratios and noted that this relationship may be attributable to mismatched thermal expansion coefficients.…”

The thermal and mechanical, near-resonant responses of particulate composite plates formed from hydroxyl-terminated polybutadiene (HTPB) binder and varying volume ratios of ammonium chloride (NH4Cl) particles (50, 65, 75%) are investigated. Each test specimen is clamped and forced with three levels of band-limited, white noise inertial excitation (10–1000 Hz at 1.00, 1.86 and 2.44 g RMS). The mechanical response of each plate is recorded via scanning laser Doppler vibrometry. The plates are then excited at a single resonant frequency and the thermal response is recorded via infrared thermography. Comparisons are made between the mechanical operational deflection shapes of each plate and spatial temperature distributions, with correlation seen between the observed level of strain, as visualized by strain energy density, and heat generation. The effect of particle/binder ratio on both the thermal and mechanical responses is discussed. Acquired results are also compared to an analytical model of the system. The observed thermomechanical effects render an improved understanding of the thermomechanics of plastic-bonded composites, an essential step in support of the development of new technologies for the vapor-based detection of hidden explosives.
