T1 MODELING SOLID-LIQUID HOMOGENEOUS TURBULENT FLOW OF NEUTRALLY BUOYANT PARTICLES USING THE MIXTURE MODEL: A STUDY OF LENGTH SCALES AND CLOSURE COEFFICIENTS JF Multiphase Science and Technology JO MST YR 2014 FD 2015-05-05 VO 26 IS 3 SP 199 OP 227 K1 mixture model K1 homogeneous solid-liquid suspensions K1 turbulence scales K1 closure coefficients K1 buoyant particles AB Numerical studies employing the mixture model were used to evaluate, through sensitivity analysis, the influence of closure coefficients and turbulence scales on a fully developed homogeneous solid-liquid suspension flow. A standard k-ε turbulence model was employed with a 20% increase for each closure coefficient; its effect was evaluated and compared with results in the literature. For turbulence length scales, several methods described in the literature served as references. The numerical results of the mixture model simulations, for a fully developed homogenous flow of solid-liquid suspensions in a circular pipe section, were compared with those in the literature. Overall, the obtained results and the literature results matched, validating the model for use with fully developed flow of neutrally buoyant particle suspensions.
