Hydrogen Burner Control Valves

我的项目将开发流体阀技术，以控制未来燃气涡轮机发动机中的氢燃料流量。该研究是与劳斯莱斯公司合作进行的，该公司已将氢动力飞行确定为航空业实现净零排放的关键技术。流体阀可用于控制流体的流动，没有移动部件，因此非常可靠。该项目的主要目标是开发一种阀门，用于控制进入燃烧室的氢气流量，并在发动机代表性压力比下运行。这个项目将坐在流体动力学和控制理论的交叉点。尺度分辨计算流体动力学，包括大涡模拟，将用于生成降阶模型。新的降维技术，如动态模式分解将被利用。这些模型将为阀门的设计提供信息，并用于开发开环和闭环控制策略。将模拟对包括燃烧室不稳定性、发动机振动和传感器噪声在内的外部干扰的鲁棒性，并通过实验活动验证原型设计。

My project will develop fluidic valve technologies to control hydrogen fuel flow within future gas turbine engines. This research is conducted in partnership with Rolls Royce PLC which has identified hydrogen powered flight as a key technology to achieving net zero within the aviation industry. Fluidic valves can be utilised to control the flow of fluids with no moving parts and are thus highly reliable. The key objective of this project is to develop a valve controlling the flow of hydrogen into the combustor operating at engine-representative pressure ratios. This project will sit at the intersection of fluid dynamics and control theory. Scale-resolving computational fluid dynamics, including large eddy simulations, will be used to generate reduced order models. Novel dimensional reduction techniques such as dynamic mode decomposition will be utilised. These models will inform the design of the valve as well as being used to develop open-loop and closed loop control strategies. Robustness to exogenous disturbances including combustor instabilities, engine vibrations, and sensor noise will be simulated and the protype designs will be validated by experimental campaigns.
