Modular Gas Turbine - Aerodynamic and Thermodynamic design of Heat Management Systems (Accelerating Net Zero using Advanced Fluids).

在推动实现“净零”的过程中，有必要在能源行业内提出和确定进一步的技术进步，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，这些进步必须在利用能源系统中实现更高的系统效率和最小化的操作损失。因此，该项目旨在研究具有理想输运特性（如低粘度到高传热能力）的先进工质，以在先进的涡轮机械动力循环中运行，以帮助实现这一转变。这些先进的工作流体含有超临界流体（如sCO2）和有机蒸汽密集气体，这些气体已经在利用sCO2的有机朗肯循环的先进循环配置中直接发现。所述流体的适用性是在这些动力循环的热管理系统中发现的，例如用于热回收或中冷，其目的是直接提高循环本身的循环效率。使用这些高工作压力高级流体可以实现高功率密度，从而可以提高效率并减小工厂规模，从而直接影响工厂的成本和规模。因此，该研究旨在解决三个关键标准：1。确定在热管理系统中使用先进工质所观察到的传热趋势。2. 正在观察的空气动力损失机制和对热管理系统本身的性能和效率的净影响。3. 在设计标准和操作条件方面提出了先进流体/流体被认为是最合适的竞争者的前进方向。这些标准将通过高保真尺度解决计算模拟的组合来解决，并通过拟议的传热设备和已经存在的空气动力损失分析设备的实验进一步验证，该设备将适应更高的超临界操作条件。

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.
