Modelling of Real Gas Compression Using the Finite Volume Thermofluid Network Methodology and Mean-Line Approach for Centrifugal Compressors

Ryno Laubscher,
Pieter Rousseau,
Johan van der Spuy
et al.

Abstract: A novel compressible real gas 1D finite volume thermofluid network modelling methodology is proposed that can be applied in the analysis of supercritical CO2 (sCO2) power cycles. It is applied to simulate centrifugal compressor performance via a mean line approach that directly solves the mass, energy, and momentum balance equations for the discretized flow channels within the machine along with the associated loss models, component characteristics, and applicable compressible real gas equation of state.
