Thermosyphons: Past, Present, and Future

Описание: Instructors: Ed Yarmak, P.E. (Arctic Foundations, Inc., Anchorage, AK); and Dr. Anna Wagner (Cold Regions Research and Engineering Laboratory (CRREL), Fairbanks, AK)

Content of Webinar: Introduction to the use of two-phase thermosyphons to maintain or augment permafrost in a variety of applications. Operation and deployment history of various thermosyphon design milestones will be presented. Several configurations of thermosyphons will be discussed as well as good practices for design. Current research and projections for the future will be presented.
