The dynamics of the transported powder determines functionality and safety pneumatic conveying systems. relation between carrier gas flow, induced by flown-through geometry, flow pattern is not clear yet for electrostatically charged particles. This paper highlights influence relatively minor cross-sectional secondary flows electrostatic forces on concentration To this end, direct numerical sim...

A numerical study, using the volume-of-fluid method (VOF), has been made of core-annular flow in a curved pipe. We investigated two cases: core-annular flow in a 90◦ bend and in a 180◦ return bend. To verify our numerical method we first compared our results for a singlephase flow in a 90◦ bend with numerical results and experimental data given in the literature. The agreement was good. Thereaf...

We propose an adaptive flow-level multipath routing-based traffic engineering solution for an IP backbone network carrying TCP/IP traffic. Incoming TCP flows are switched between two explicitly routed paths, namely the primary and secondary paths, for resilience and potential goodput improvement at the TCP layer. In the proposed architecture, primary paths receive a preferential treatment over ...
