Scalar features in fluid flow are traditionally visualized with glyphs or using direct 3D representation, and their topology changes over time are often conveyed with abstract graphs. Using these techniques, however, the spatio-temporal evolution of features undergoing topological changes is difficult to analyze. In this paper, we propose a novel approach for the visualization of the dynamics o...

This paper presents a novel approach for simulating incompressible two-phase flows by combining a conservative level set technique and the ghost-fluid method. Following the ideas of Olsson and Kreiss (2005), the liquid-gas interface is localized using a hyperbolic tangent level set that is transported and reinitialized using fully conservative numerical schemes. Mass conservation issues are gre...

A reliable description of dense gas–solid two-phase flows of Geldart A particles in gasfluidized beds at life-size scale is of great practical importance in process industries. The classical two-fluid model, based on the kinetic theory of granular flows (KTGF), provides a very promising theoretical framework for predicting large-scale gas–solid twophase flows. However, thus far the two fluid mo...
