Research projects
The following research projects are being worked on or were worked on by Prof. Kretzschmar and his colleagues:
BMWi Project "Fast calculation of real properties in ATHLET according to the latest IAPWS standards (SBRS – AC2)"
This process, developed in the field of technical thermodynamics, for the fast and precise calculation of thermodynamic properties with the "Spline-Based Table Look-Up Method" (SBTL) is integrated into the reactor safety code ATHLET.
Partner:
- Association for Reactor Safety, Munich (Gesellschaft für Reaktorsicherheit (GRS) München)
Current work:
- Analysis of the requirements for property calculation in the various calculation models from ATHLET
- Development of a new property library with the SBTL method on the basis of the scientific IAPWS standards
ASHRAE Project "SPC 213 – Method for Calculating Moist Air Thermodynamic Properties"
A new standard for calculating the thermodynamic properties of humid air is being developed on behalf of the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE).
Partners:
- American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE)
- University of Maryland, College Park, MA (USA)
Current work:
- Verification of the calculation model developed
ASHRAE Research Project "RP 1767 – Moist Air Transport Properties Research"
A new procedure for calculating the transport properties of humid air is being developed on behalf of the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE).
Partners:
- American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE)
- University of Maryland, College Park, MA (USA)
Current work:
- Further development of the procedure for calculating the transport properties of humid air
