A general objective of this project was to develop, verify and validate mechanistic multidimensional models of local flow and heat transfer in supercritical carbon dioxide (S-CO₂) devices and systems, and to demonstrate the application of the new models to selected components of S-CO₂ nuclear energy transport systems. Both steady-state and time-dependent operating conditions have been investigated. The overall workscope consisted of the following three major parts: Development, testing and validation of a mechanistic model of forced-convection heat transfer in heated channels cooled using S-CO₂ at slightly supercritical pressures; Development, testing and verification/validation of a new model of the dynamics of closed- loop S-CO₂ heat transport systems; and, Formulation, testing and verification of a mechanistic model for the analysis of flow and pressure distribution in S-CO₂ compressors. The results of the work performed for the project have been documented in several publications.
