Aerothermal support for TMT International Observatory enclosure and summit facilities subsystems
17 June 2024 • 14:40 - 15:00 Japan Standard Time | Room G403/404, North - 4F
Abstract
Computational Fluid Dynamics (CFD) and conjugate heat transfer models have been developed and/or updated to validate thermal requirements for the TMT International Observatory enclosure Heating, Ventilation and Air Conditioning (HVAC) system, azimuth and cap drive systems, interstitial space volume, as well as the Summit Facilities tunnel, mechanical room, utility room, and cooler exhaust. The resulting thermal environment is assessed and linked to performance, wherever applicable.

Dr. Konstantinos Vogiatzis is a Consultant.
He has been involved in the design and/or performance analysis and improvement of several ground-based observatories such as TMT, GMT, LSST, Keck, CFHT, DKIST, and Gemini, since he joined the National Optical Astronomy Observatories in 2002 and later the Thirty Meter Telescope in 2006. From 2014 to 2019 he was also the CFD Lead for the DoD user Productivity Enhancement, Technology Transfer and Training Program, being a Technical Fellow at Engility Corporation (later SAIC). He also acts the Chief Research Scientist at Next Frontier LLC, providing support to the US Air Force mainly in the fields of hypersonic flow, aero-optics and mesh generation.
He has a Doctorate degree in Engineering Science from Louisiana State University with minors in Astrophysics and Oceanography (2001) and a Diploma in Mechanical Engineering from the National Technical University of Athens, Greece (1992).
