On the modeling of dispersed particulate flows using a multified model

Publisher Summary This chapter discusses the selected computational and modeling issues associated with the usage of multifield modeling framework to perform computational fluid dynamics (CFD) simulations of multiphase flows. An approach is proposed to resolve an apparent multifield modeling inconsistency of an induced shear–stress correction term. The implementation of this correction term and other convergence improving algorithms into the NPHASE solver is also discussed. The range of applications and accuracy of predictions of the multifield model strongly depend on the degree to which the closure laws. The results of model testing are shown for dispersed particulate flows in a variety of geometries, such as straight pipes, a U-bend, and a helical tube.
