Special Topics in Xist Short Course

Course Fee: US$650

This short course moves beyond the fundamentals of thermal design to focus on specific design challenges associated with a range of service types including viscous shellside coolers, feed-effluent exchangers, kettle reboilers, and vacuum condensers. Presented as a series of case studies, each topic is introduced by the instructor before participants delve into Xist to work on solutions which are ultimately discussed amongst the group. The knowledge attained from this short course will allow you to tackle related design challenges in your future work.

Key Topics

  • viscous shellside coolers
  • feed-effluent exchangers

  • Lauren V. Moran

  • Manager, Technical Support, joined HTRI after having worked for five years with two National Aeronautics and Space Administration (NASA) contractors at the Johnson Space Center in the Houston, Texas (TX), USA: McDonald Detwiller and Associates Ltd. (MDA) and Science Applications International Corporation (SAIC). Her responsibilities as a Systems Engineer focused on projects related to the International Space Station. She was certified as a console extravehicular robotics engineer and safety engineer in the Mission Control Center and also served as technical liaison between Boeing and the Canadian Space Agency. Moran now provides technical support and training to HTRI members and assists in contracts and troubleshooting heat exchangers. She earned a BS in Engineering from LeTourneau University, Longview, Texas.
