项目摘要

Overview and aims of the SuperCO2 project: The supercritical carbon dioxide (sCO2) cycle is a promising power generation technology with the advantages of compactness, efficiency, high safety and environmental friendliness. However, the phase transition of sCO2 near the critical point, one of the salient issues affecting long term operability and reliability of sCO2 systems, is still not fully understood due to the complicated flow behaviour in supercritical-gas-liquid phase transitions accompanied by heat and mass transfer processes. The proposed project aims to reveal the fundamental understanding of the nonequilibrium condensation of sCO2 in transonic flows and potentially promote the development of the next-generation clean, efficient power cycle.Contribution of SuperCO2 project: The proposed project will contribute to the understanding of the nonequilibrium condensation of sCO2 in transonic flows by proposing experimental and numerical studies. This model is able to precisely determine the formation and growth of nanodroplets with heat and mass transfer during the sCO2 phase transition. The proposed project providing a deep understanding of the phase transition of the sCO2 near the critical point, which will not only reduce thermodynamic and aerodynamic losses but also improve the reliability and life of turbine components, goes beyond the state-of-the-art of understanding of the current sCO2 technology. Thus, the sCO2 project shows a breakthrough ambition to potentially promote the development of a new generation of power cycles. More than 4 papers are expected to be published in prestigious peer-reviewed journals. Duo to wide applications of the sCO2 cycles, this unique project will not only be helpful to the European power industry, including the R&D of new power generation technology but also will promote the fundamental research level in related areas, such as supercritical fluid flow and condensation dynamics.

SuperCO2项目概述及目标：超临界二氧化碳（sCO2）循环是一种很有前景的发电技术，具有紧凑、高效、安全性高、环境友好等优点。然而，由于超临界-气-液相变过程中伴随着热量和热量的复杂流动行为，sCO2在临界点附近的相变是影响sCO2系统长期运行和可靠性的突出问题之一，目前仍未得到充分理解。传质过程。该项目旨在揭示跨音速流中 sCO2 非平衡凝结的基本认识，并有可能促进下一代清洁、高效动力循环的发展。 SuperCO2 项目的贡献：该项目将有助于理解非平衡凝结通过提出实验和数值研究来研究跨音速流中 sCO2 的凝结。该模型能够精确确定 sCO2 相变过程中纳米液滴的形成和生长以及传热和传质。拟议的项目深入了解了临界点附近的 sCO2 相变，这不仅可以减少热力学和空气动力学损失，还可以提高涡轮机部件的可靠性和寿命，超越了现有技术水平。了解当前的 sCO2 技术。因此，sCO2项目展现了突破性的雄心，有可能推动新一代动力循环的发展。预计将有超过 4 篇论文发表在著名的同行评审期刊上。由于sCO2循环的广泛应用，这一独特的项目不仅有助于欧洲电力工业，包括新型发电技术的研发，而且将促进超临界流体流动和冷凝等相关领域的基础研究水平动力学。
