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是一个博士网络，旨在培养早期研究人员，能够面对基于电磁辅助燃烧的创新尖端技术领域当前和未来的挑战，以实现对氢火焰的完全控制。ICHAruS的建立是为了在学术机构和欧洲主要燃气涡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，该合作伙伴关系的目的是了解在所有流量尺度下控制氢气燃烧和电磁场之间相互作用的物理过程，以实现火焰控制并确定关键参数，从而设计出创新的超低NOx和防回火燃烧装置。通过等离子体放电和电磁调节来控制氢火焰，为大力加速能源和交通领域的零碳发展提供了机会。将追求三个具体的研究目标：1）研究和模拟电磁场对物种传输和化学动力学的影响，以揭示外部电磁场对纯氧和空气中氢的反应化学的影响，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的影响，而不是电磁漂移。2)低能量和高能量电磁辅助燃烧的紊流燃烧模型的发展。将研究电磁漂移和湍流传输之间的竞争效应，并开发考虑电磁场和等离子体效应的大涡模拟的次网格尺度闭合。3)创新的电磁辅助控制技术的实验和数值研究，用于实际感兴趣的火焰稳定。单旋流火焰和环形结构都将被研究。燃料分级和喷射也将作为在现实发动机中实际实施的基本步骤进行研究。
