Engineering Physics Colloquium

Tuesday, October 16

4:00 PM to 5:00 PM

106 Engineering Research Building

Speaker:  Dr. Anton Moisseytsev, Argonne National Laboratory
"Modeling of the Supercritical Carbon Dioxide Brayton Cycle or Why Nuclear Engineers Need Classes in Turbomachinery, Art, and Everything in Between"
Abstract:  Supercritical carbon dioxide (S-CO2) Brayton cycles offer potential advantages over other power converter systems in terms of the higher cycle efficiency and remarkably small turbomachinery. The cycle benefits originate from the CO2 properties behavior near the critical point. To accurately simulate the cycle performance and transient behavior, one needs to pay close attention to the effect of the properties variation on the performance of the turbomachinery, heat exchangers, control mechanisms , and other components. Many, if not all, existing "commercial" codes either ignore some of these effects or simply fail to converge in the proximity of the critical point. The presentation discusses the development of the Plant Dynamics Code at Argonne National Laboratory for the design and transient analysis of the S-CO2 cycle for nuclear power reactor applications and describes various engineering disciplines involved in modeling the cycle.
Biography:  Dr. Anton Moisseytsev is a Principal Computational Nuclear Engineer at Nuclear Engineering Division of Argonne National Laboratory. He has eight years of experience in modeling and simulation of various reactor systems, including design and analysis of the advanced reactors and energy conversion systems, safety analysis of nuclear reactors, and code development for steady-state and transient simulations of nuclear power plants. Anton has been involved in the development of the supercritical carbon dioxide Brayton cycle at Argonne since 2002.
Event Note:  3:45 PM refreshments will be served.
