SUPERCRITICAL CO2 - Flownex Simulation Environment · Well de˜ned two-phase CO2 ˚uid properties Detailed ˚uid dynamic models (choking, real gas behavior, etc.) Incremental heat

Flownex® SE simultaneously solves mass, momentum and energy in conjunc-tion with two-phase fluid properties for system models. This makes it ideal for modelling supercritical CO2 cycles where key design parameters can be analyzed and optimized.

BRINGING NUCLEARQUALITY AND STANDARDSTO SYSTEM SIMULATION

Flownex® is developed in anISO 9001:2015 quality assurance systemand NQA1 supplier approved environment.

The Indian Institute of Science, Bangalore, uses

Flownex to extensively model the transient oper-

ation of their 100kW sCO2 test loop. The predicted thermo-

dynamic states of components are used to develop advanced

control algorithms and stable operational regimes.
