Investigating the fluid dynamics and heat transfer aspect of the ultra-high temperature thermal energy storage technology being developed by Dr Adam Robinson in the Institute of Energy Systems at the University of Edinburgh.I'd be designing and evaluating the use of heat pumps to charge the storage core and to recirculate waste heat to maintain the core temperature. I'd also be investigating if using blade cooling in the heat pump results in acceptably low thermodynamic losses, and more generally investigating the aerodynamic considerations and heat transfer in the heat exchangers. I'd be designing a valve to switch between using hot combustion products in the power generating gas turbine, and nitrogen heated from the storage core. I'd also be investigating the reheat system used in the power generating gas turbine.The work would involve writing computer code to take account of the additional effects of heat transfer and structural considerations in computational fluid dynamic simulations. Mathematical models of the various system components would be developed and compared with experimental data obtained from a scaled down test rig of the thermal energy store. It would also be desirable to develop a numerical model of the complete system in order to perform transient analyses.

爱丁堡大学能源系统研究所的亚当·罗宾逊博士正在研究超高温储能技术的流体动力学和热传递方面的问题。我将设计和评估使用热泵为储能核心充电并将废热循环以保持核心温度的使用。我还将调查在热泵中使用叶片冷却是否会导致可接受的低热力学损失，以及更广泛地调查热交换器中的空气动力学考虑和热传递。我将设计一种阀门，在发电燃气轮机中使用热燃烧产品和从存储核心加热氮气之间进行切换。我还将研究发电燃气轮机中使用的再热系统。这项工作将涉及编写计算机代码，以考虑计算流体动力学模拟中的热传递和结构考虑的额外影响。将建立各种系统组件的数学模型，并将其与从热能存储的缩小试验台获得的实验数据进行比较。为了进行暂态分析，还需要开发一个完整系统的数值模型。
