MTU Aero Engines, Germany's leading aircraft engine manufacturer, recognizes that, in order to secure a sustainable future for long-haul air transportation, it will be necessary to transition to bio-fuels; this will necessitate a sea-change in the design of future gas turbines to permit fuel flexibility. Much of the design of current gas turbine combustion chambers is based on prior knowledge; the models currently used in combustor design tend to be empirical in nature and are tuned based on the performance using fossil fuels. There is a clear need for improvements to these tools in such a way as to account for the effects of changing the fuel. The UBC combustion simulation group under Dr. Bushe offers an innovative alternative methodology, the Uniform Conditional State combustion model, which uses significantly less computational resources than other methods while providing significant improvement in the predictive capabilities. The new approach allows for a much wider range of fuels to be simulated and has been embedded in a free, open-source Computational Fluid Dynamics package that MTU uses in their simulations of gas turbine combustors.Further improvements to the modelling are needed to allow predictions of heat transfer to solid surfaces inside the combustion chamber and improved predictions of the emissions of pollutants. The aim of this project is to demonstrate that the tools under development can provide accurate predictions of pollutants and heat transfer for flames of jet fuel A in air, in addition to flames with alternative, low-sooting fuels such as methanol, DME and OMEs - fuels that can be made relatively easily from biological sources with a high yield, and, as such, may ultimately be produced sustainably. Working with MTU Aero Engines, Dr. Bushe and his students in the combustion simulation group at UBC will develop the needed improvements to - and validation of - these models so that the resulting computational tool will be useful for design for these next-generation fuels for jet propulsion.

德国领先的飞机发动机制造商MTU航空发动机公司认识到，为了确保长途航空运输的可持续发展，有必要过渡到生物燃料;这将需要对未来燃气轮机的设计进行彻底改变，以允许燃料的灵活性。 当前燃气涡轮机燃烧室的大部分设计是基于先验知识;当前用于燃烧器设计的模型在本质上倾向于经验性的，并且基于使用化石燃料的性能来调整。 显然需要改进这些工具，以便考虑到改变燃料的影响。 Bushe博士领导的UBC燃烧模拟小组提供了一种创新的替代方法，即均匀条件状态燃烧模型，该模型使用的计算资源比其他方法少得多，同时在预测能力方面有显着提高。 这种新方法允许模拟更广泛的燃料，并已嵌入到MTU用于模拟燃气涡轮机燃烧室的免费开源计算流体动力学软件包中。需要进一步改进建模，以预测燃烧室内固体表面的热传递，并改进污染物排放预测。该项目的目的是证明，正在开发的工具可以提供准确的预测污染物和空气中喷气燃料A火焰的热传递，除了与替代燃料，如甲醇，DME和OME的火焰-燃料可以相对容易地从生物来源以高产率制成，因此，最终可以可持续地生产。 Bushe博士和他在UBC燃烧模拟小组的学生们将与MTU航空发动机公司合作，对这些模型进行必要的改进和验证，以便由此产生的计算工具将有助于设计这些用于喷气推进的下一代燃料。
