Phase Transformation and Deformation Model for Quenching Simulations

Y. Kaymak [1],
[1] VDEh Betriebsforschungsinstitute GmbH, Düsseldorf, Germany

Heat treatment of the advanced steel grades (like micro-alloyed steels or AHSS steel grades) is a challenging process as the residual stress/deformation are very pronounced and the customer quality requirements are getting stricter. Instead of a trial and error based process control, a ... Read More

Validation of COMSOL Multiphysics® for Magnetohydrodynamics (MHD) Flows in Fusion Applications

Y. Yan [1], S. Smolentsev [1], M. Abdou [1]
[1] Fusion Science and Technology Center, University of California, Los Angeles, CA, USA

Several commercial CFD companies have recently extended their codes to magnetohydrodynamic (MHD) flows. However, there are many computational challenges associated with MHD flows under the harsh fusion environmental conditions that require such codes to be carefully examined in a special ... Read More

Multiphysics Modeling of the Graphite Electrode Joint in Electric Arc Furnaces for Steel Recycling

N. May [1], M. Waldner [2],
[1] GrafTech International Holdings, Inc., Independence, OH, USA
[2] Case Western Reserve University, Cleveland, OH, USA

Electric Arc Furnaces (EAF) use graphite electrodes to strike an arc to melt scrap steel, recycling it for further use. These graphite electrodes oxidize and are consumed over time. To maintain operation new electrodes are attached to others via a joint of complex geometry and fed ... Read More
