Improved tools for the prediction of combustion inside gas turbines

MTU航空发动机是德国领先的飞机发动机制造商，也是该行业老牌的全球参与者。该公司从事所有推力和动力类别的商用和军用飞机发动机以及固定式燃气轮机的设计、开发、制造、营销和支持。MTU维护加拿大公司是MTU维护公司网络的北美成员，该公司代表着全球最大的独立商用飞机发动机服务提供商。为了保持和提高他们在燃烧技术方面的能力水平，MTU Maintenance Canada和MTU航空发动机公司希望为W.Kendal Bushe教授和他的学生的研究提供资金支持，并在整个过程中提供他们的专业知识和建议。燃烧研究方面的专业知识大多掌握在慕尼黑MTU手中，但最近有一些努力将部分知识转移到加拿大。随着MTU新的维修合同即将到来，加拿大有雄心为各种航空发动机部件开发和实施新的和创新的维修方法。这将在未来几年实现可持续的维护战略。为了了解和评估燃烧室内和燃烧室附近高温的影响，利用燃烧模拟改进定性和定量预测是至关重要的。布什博士领导的研究小组提供了Demand方面的专业知识和一种创新的替代方法，即条件源术语估计(CSE)燃烧模型，该模型使用的计算资源比其他方法少得多。此外，布什博士和他的博士生格雷厄姆·亨德拉提出了一个密切相关的新模型，他们将其命名为统一条件状态模型；这种新方法将允许在燃烧化学建模方式方面有更大的灵活性，这应该允许纳入任意复杂的化学动力学机制，以便可以模拟更广泛的燃料的燃烧。这些方法将提供一种工具，使MTU能够制定新的、可持续的维护战略。

MTU Aero Engines is Germany's leading aircraft engine manufacturer and an established global player in the industry. The company engages in the design, development, manufacture, marketing and support of commercial and military aircraft engines in all thrust and power categories and stationary gas turbines. MTU Maintenance Canada is the North American member of the MTU Maintenance network of companies, which represents the largest provider of independent commercial airplane engine services worldwide. In order to maintain and improve their level of competence in combustion technology MTU Maintenance Canada and MTU Aero Engines want to support financially the research of Prof. W. Kendal Bushe and his students and to offer their expertise and advise throughout the process. Mostly the expertise in combustion research resides with MTU Munich, but there have been recent efforts to transfer part of that knowledge into Canada. With upcoming new maintenance contracts for MTU Canada has the ambition to develop and implement new and innovative repair methods for various aero engine components. This will enable a sustainable maintenance strategy for the years to come. To understand and evaluate the effects of the high temperatures in and near the combustion chamber, the improvement of qualitative and quantitative predictions using combustion simulation is essential. The research group under Dr. Bushe offers the expertise in demand and an innovative alternative methodology, the Conditional Source-term Estimation (CSE) combustion model, which uses significantly less computational resources than other methods. Further, Dr. Bushe and his PhD student, Graham Hendra, have proposed a new, closely related model which they are naming the Uniform Conditional State model; this new approach will allow for more flexibility with respect to the way combustion chemistry is modelled, which should allow for incorporating arbitrarily complex chemical kinetic mechanisms, such that combustion of a much wider range of fuels can be simulated. These approaches will provide a tool which will enable MTU to develop new, sustainable maintenance strategies.
