Optimized design and analysis of turbomachinery and heat exchangers for supercritical CO2 systems

The primary objective of the research program is to extend the proprietary ARGO® code with modules for the optimized sizing of:- Variable-angle Inlet Guide Vanes (IGVs) for centrifugal compressors operating with transcritical and supercritical CO2- Compact PCHE heat exchangers for recompressed Brayton-Joule cycles operating with CO2 in vapor or twophase (liquid/vapor) conditions.In addition to the aforementioned code expansion, the research activities include:- Application of the ARGO® code to the sizing of components for a highly flexible supercritical CO2 power plant;- Detailed analysis, through three-dimensional CFD simulations, of the preliminary solutions generated using the ARGO® code;- Evaluation, using the commercial code ChemCAD, of the system performance under nominal and partial load conditions.
