The study focuses on the thermo-hydraulic performance<\/strong> of a printed circuit heat exchanger (PCHE)<\/strong> operating with supercritical carbon dioxide (sCO\u2082)<\/strong> \u2014 a working fluid at the core of DESOLINATION\u2019s innovative power block. PCHEs are a compact and high-efficiency solution suitable for the extreme conditions of sCO\u2082-based energy systems, such as those integrated into concentrated solar power (CSP) and desalination technologies.<\/p>\n

Using a combination of experimental testing<\/strong> and computational fluid dynamics (CFD)<\/strong>, the team evaluated the heat transfer and pressure drop characteristics of sCO\u2082 flowing through PCHE microchannels. The study targeted the pseudo-critical region<\/strong>, where CO\u2082 exhibits rapid property variations that enhance heat transfer but complicate predictive modelling.<\/p>\n<\/div>\n

This work directly contributes to DESOLINATION\u2019s goal of developing an efficient, solar-powered desalination system<\/strong> by improving the performance prediction and design of key components in the sCO\u2082 power cycle. In particular, it provides validated tools and insights essential for integrating high-efficiency heat exchangers<\/strong> into the project\u2019s future demonstration plant.<\/p>\n

  • Experimental data<\/strong> were gathered under a wide range of operating conditions at LUT University\u2019s transcritical CO\u2082 test facility, providing a valuable benchmark for validation of numerical models.<\/li>\n
  • The CFD simulations<\/strong>, incorporating real-gas behaviour and the SST k-\u03c9 turbulence model, showed good agreement with the measured pressure drops and outlet temperatures.<\/li>\n
  • A new friction factor correlation<\/strong> was derived from the experimental results. It accounts for surface roughness and achieved a prediction accuracy within \u00b110% of the measured values \u2014 an important advancement over existing correlations.<\/li>\n
  • The study also revealed that commonly used heat transfer correlations<\/strong> tend to underestimate performance<\/strong> in high-Reynolds number, sCO\u2082 microchannel flows, underlining the need for more tailored predictive models.<\/li>\n<\/ul>\n
