In the push towards achieving "Net Zero" it is necessary that further technological advancements within the energy industry are proposed and identified in order to reduce plant costs, improve plant efficiencies and allow for plant adaptability with other renewable energy sources. These advancements hence must achieve higher system efficiencies with minimised operating losses in the utilised energy systems. Thus, this project aims to research advanced working fluids with desirable transport properties (such as low viscosity to high heat transfer capability) to operate in advanced turbomachine-based power cycles to aid in this transition. These advanced working fluids contain Supercritical fluids (such as sCO2) and organic vapour dense gases which are already directly found within advanced cycle configurations utilising organic Rankine cycles of SCO2 recovery. Applicability for said fluids is found within the heat management systems of these power cycles such as for heat recovery or intercooling which aims to directly push the cyclic efficiency further for the cycle itself. The achievable high power-densities with the use of these high operating pressure advanced fluids can thus allow for higher efficiencies and reduced plant size thus, directly influencing plant cost and size. Thus, the research aims to address three key criterions 1. Identify heat transfer trends observed with the use of proposed advanced working fluids in heat management systems. 2. Aerodynamic loss mechanisms being observed and the net effect on performance and efficiencies of the heat management system itself. 3. Proposed way forward in terms of design criterion and operating conditions for advanced fluid/fluids deemed as the best suitable contenders. These criterions shall be addressed through a combination of high-fidelity scale resolving computational simulations and further verification through experimentation with a proposed heat transfer facility and an already existing facility for aerodynamic loss analysis which will be adapted for higher supercritical operating conditions.

在推动实现“净零”的过程中，有必要提出和确定能源行业内的进一步技术进步，以降低工厂成本、提高工厂效率并允许工厂适应其他可再生能源。因此，这些进步必须实现更高的系统效率，同时最大限度地减少所用能源系统的运行损失。因此，该项目旨在研究具有理想传输特性（例如低粘度到高传热能力）的先进工作流体，以在先进的基于涡轮机的动力循环中运行，以帮助实现这一转变。这些先进的工作流体包含超临界流体（例如 sCO2）和有机蒸汽致密气体，这些气体已直接在利用 SCO2 回收的有机朗肯循环的先进循环配置中找到。所述流体适用于这些动力循环的热管理系统，例如用于热回收或中间冷却，其目的是直接进一步推动循环本身的循环效率。使用这些高工作压力先进流体可实现高功率密度，从而提高效率并缩小工厂规模，从而直接影响工厂成本和规模。因此，本研究旨在解决三个关键标准： 1. 确定在热管理系统中使用所提出的先进工作流体时观察到的传热趋势。 2. 观察到的空气动力学损失机制以及对热管理系统本身的性能和效率的净影响。 3. 在先进流体/被认为是最合适的竞争者的流体的设计标准和操作条件方面提出的前进方向。这些标准应通过高保真规模解析计算模拟的结合以及通过使用拟议的传热设施和现有的空气动力损失分析设施进行实验进一步验证来解决，该设施将适用于更高的超临界操作条件。
