Supersonic Jet Creating Turbulent Mixing (University of Rochester) Hardware needs: 3 SGI Origin 2000s, each with 16 IR pipes, 128 CPUs and 128 GB of memory. An SGI Onyx 3900 with 34 ATI pipes, 80 CPUs and 80 G of memory. 29 TB of shared RAID disk for visualization. Hardware Diagram Active galactic nuclei are often observed to launch high speed jets of material from their poles which propagate out into the low density intergalactic medium for distances of many light years.
Exhaust Manifold Analysis (FSI) Efficient pre- and post-processing is most important in CFD. ADINA CFD can now also be used with EnSight. In this News, we illustrate such use by considering the Thermal CFD and Stress Problem of an Exhaust Manifold that already was solved in the News of June 15, 2007.
