ABSTRACT
GTI is performing transient analysis using Flownex to model the 10 MWe sCO2 Brayton test facility being built on the Southwest Research Institute (SwRI) campus in San Antonio, Texas. Flownex is an object-oriented simulation environment that was developed in the late 1980s. It is ISO 9001:2008 and NQA1 compliant and has been validated in the nuclear industry. GTI has built models for both the simple Brayton cycle and recompression Brayton cycle (RCBC) configurations that will be tested in the facility. The steady state results of the model have been benchmarked against the Aspen Plus steady state model results for the design condition. This paper will review the implementation of components into Flownex and the control guidance from the model provided by the results of a startup simulation.
