Накратко на български

Топлообменниците със свръхкритичен въглероден диоксид се анализират чрез симулации и тестове, за да се разбере как се движи топлинният поток при слънчевата енергия. Това помага за създаването на по-ефективни системи за чиста енергия, което допринася за намаляване на въглеродните емисии.

Coupled heat transfer and thermodynamic optimization of supercritical CO2 heat exchangers

The supercritical CO2 (SCO2) Brayton cycle system with the advantages of high efficiency and high compactness is very suitable for clean and renewable energy like solar energy. Compared with other energy storage technologies, transcritical or supercritical CO2 energy storage technology has the advantages of low cost, high efficiency, and fewer constraints, and has a promising application potential. Whether it is a supercritical or transcritical CO2 energy system, it faces a practical technical problem. The thermophysical properties of CO2 change drastically in the regions near the critical point or pseudo-critical point, making thermodynamic processes such as heat transfer and flow extremely complex processes, far from being fully understood or well predicted. To address these problems, this project employed a research method combining theoretical analysis, numerical simulation and experimental testing, to study the characteristics of heat transfer and flow of SCO2 to improve and develop novel power systems by harnessing the unique properties of CO2 for renewables, especially solar power. The project is conducive to the large-scale development and utilization of clean energy (like solar energy), so as to reduce carbon emissions and achieve carbon neutrality to cope with climate change.

Цел на проекта

The clean energy and its efficient utilization are effective solutions for the energy security, health and environmental pollution, which are highly promoted in Work Programme 2018-2020. The supercritical CO2 Brayton cycle has a great potential to generate clean power from sources such as solar energy and safer new-generation nuclear reactors. Heat exchangers play a crucial role on the cycle efficiency, safety and stability of the system. However, the sharply variable properties of CO2 through the components make heat transfer an extremely complex process, which is far from being fully comprehended or well-predicted, and seriously challenge conventional heat exchanger design and optimization theories and tools, thereby hindering further system development, implementation and uptake. To address these issues, this proposal attempts to perform first-of-a-kind measurements using the advanced optical (laser-based) diagnostic techniques and IR thermography simultaneously, which will provide previously-unavailable data and develop advanced tools for the prediction of the flow and heat transfer characteristics of supercritical fluids. Furthermore, a new optimization design method will be developed based on the piecewise design method and thermodynamic theory which can treat the coupled heat transfer problem on both sides of a heat exchanger, overcoming the problems with the existing single-side approaches. This action aims to deepen our essential understanding of flow and heat transfer of supercritical fluids, and develop novel coupled heat transfer enhancement theory. This proposal will be supervised by Prof. Christos Markides at Imperial College London. The host’s academic standing and expertise, and the innovative nature of the project, ensure this action not only provides an excellent pathway for knowledge transfer, but also provides a unique opportunity for my further maturity, which is instrumental to my achieving my career goal of leading my own research team.
