[For background information on this subtopic, please see Report on Workshop on Multiphase Flow Research, Morgantown, WV, June 6-7, 2006, ed. M. Syamlal, DOE/NETL-2007/1259, December 2006, http://www.netl.doe.gov/events/06conferences/mfr_workshop/Multiphase%20Workshop% 20Report%206.pdf] Polydispersed Systems: Proposals are sought for developing continuum models of gas-solids flows that describe suspended solids with a distribution in size or density or both. The constitutive models are required for granular stresses and gas-solids drag. The granular stress models are expected to be extensions of granular kinetic theory applicable to several discrete particle types or to a particle size/density distribution. Research work may be proposed in areas such as the development of theory and advanced computational models, gathering of experimental data from physical systems or molecular dynamics simulations, and the validation of the models. Frictional Flow Regime: Proposals are sought for the development of continuum models of gassolids flows applicable to flow regimes in which the particles are in enduring contact. Although constitutive models originating from soil mechanics are available for describing dense flows, these models cannot handle the transitions from stagnant to shearing regimes and from dense flow to dilute flow (described using granular kinetic theory) regimes. Research work may be proposed in areas such as the development of theory and advanced computational models, the gathering of experimental data from physical systems or molecular dynamics simulations, and the validation of the models.
