ICHAruS is a Doctoral Network aimed to train early-stage researchers, able to face current and future challenges in the field of innovative, cutting-edge technologies based on electromagnetic-assisted combustion to achieve full control of hydrogen flames. ICHAruS has been built to provide doctoral training in a collaborative partnership between academic institutions and industry partners who are major European gas turbine manufacturers. The aim of this partnership is thus to understand the physical processes that govern the interaction between hydrogen combustion and electromagnetic fields at all flow scales, to achieve control of the flame and identify the key parameters that would allow for the design of an innovative, ultra-low NOx and flashback-proof combustion device. The control of hydrogen flames through plasma discharge and electromagnetic conditioning offers the opportunity to strongly accelerate the path towards zero-carbon energy and transport sectors. Three specific research objectives will be pursued: 1) Investigation and modelling of electromagnetic field effects on the species transport and chemical kinetics to unveil the effect of external electromagnetic fields on the reaction chemistry of hydrogen in both pure oxygen and air, and also determine any effects on the formation of pollutants. The effect of differential diffusion on the flame structure as opposed to electromagnetic drift will also be investigated. 2) Development of turbulent combustion models for low- and high-energy electromagnetic-assisted combustion. The competing effects between electromagnetic drift and turbulent transport will be investigated and sub-grid scale closures for large-eddy simulations that consider the effect of electromagnetic fields and plasma will be developed. 3) Experimental and numerical investigation of innovative electromagnetic-assisted control technologies for the stabilisation of flames of practical interest. Both single swirl flames and annular configurations will be investigated. Fuel staging and injection will also be studied as a fundamental step towards practical implementation in realistic engines.

Icharus是一个旨在培训早期研究人员的博士网络，能够在基于电磁辅助燃烧的创新，尖端技术领域面临当前和未来的挑战，以完全控制氢火焰。 Icharus旨在在学术机构与主要是欧洲燃气轮机制造商的行业合作伙伴之间的合作伙伴关系中提供博士培训。因此，这种伙伴关系的目的是了解在所有流程尺度上控制氢燃烧和电磁场之间相互作用的物理过程，以实现对火焰的控制并确定允许设计创新，超低NOX和闪回防护装置的关键参数。通过等离子体排放和电磁条件控制氢火焰，为强烈加速通往零碳能和运输部门的路径提供了机会。将实现三个特定的研究目标：1）对电磁场对物种运输和化学动力学的影响和建模，以揭示外部电磁场对纯氧和空气中氢反应化学的影响，并确定对污染物形成的任何影响。还将研究差分扩散对火焰结构而不是电磁漂移的影响。 2）开发用于低能和高能电磁辅助燃烧的湍流燃烧模型。将研究电磁漂移与湍流转运之间的竞争效应，并为大型模拟的次级网格尺度闭合，这些模拟将开发出电磁场和等离子体的影响。 3）创新电磁辅助控制技术的实验和数值研究，以稳定实际感兴趣的火焰。将研究单个漩涡火焰和环形配置。还将研究燃料分期和注入，作为迈向现实发动机实施实施的基本一步。
