Transient flow events can be very important to the generation of quality problems during the continuous casting of steel. In this work, several different tools are applied to investigate these phenomena. Transient flow is computed using Large Eddy Simulation (LES) models, while conventional K-ε models yield time-averaged results. Particle Image Velocimetry(More)
Turbulent structures are important in influencing inclusion transport in continuous casting of steel. The turbulent velocity field and inclusion transport are studied in a full-scale water model using large eddy simulations. The computed fluid velocities are compared with measurements. Chaotic vortex structures were computed in the upper roll region as(More)
Starting in 1996, the authors, Surya Vanka and Jim Budd developed ID-Online, an Asynchro-nous Learning Network (ALN) for Industrial Design Education at the University of Illinois at Urbana-Champaign. The primary objective of ID-Online was to deliver enhanced design instruction via asynchronous access to design resources and enhance network-based(More)
In the present paper, several turbulence models have been evaluated in a channel and a square duct flow with and without a magnetic field by comparing the predictions with Direct Numerical Simulations (DNS) data. The various turbulence models include high and low Reynolds number versions of the k-ε model, low and high-Re versions of the Reynolds-stress(More)
Particle motion and capture in continuous steel casters were simulated using a Lagrangian trajectory-tracking approach, based on time-dependent flow fields obtained from large eddy simulations (Part I). A computation was first conducted on a water model of a full-scale standard slab caster, where measurements were available. It simulated the transport of(More)
16. Abstract Highway relief routes may have a variety of impacts on small-and medium-size communities, both positive and negative. On the positive side, communities benefit from a reduction in traffic through the heart of the community and the negative impacts such traffic brings, including noise, emissions, and safety concerns. However, the reduction in(More)
