News from Dyrobes Training in Capon Springs, and a New Paper on Atkins and Perez Rotor Stability

The Fall Dyrobes Users Group met on October 15-19, 2017, at Capon Springs, WV, USA. Dyrobes users met for advanced modeling instruction, to review new Dyrobes features and to work on individual projects. These individual industry projects included modeling and analyzing turbo chargers, gas turbines, and turbo compressors. Participants at the workshop appreciated the opportunities to work on their Dyrobes models and analysis with one-on-one access to Dyrobes experts. As […]

The Kaybob Compressor Failure Revisited

In 1971, there was a major problem at the Kaybob South Beaverhill Lake plant in Fox Creek, Alberta. A massive compressor, comprised of three natural gas re-injection trains, became dangerously unstable and failed. To address the problem, teams of engineers spent more than five months and one hundred million modern U.S. dollars to fix the problem. The months of troubleshooting that followed the Kaybob failure demonstrate the critical importance of […]
