Experimental and Numerical Studies on High-Pressure, High-Temperature Laminar and Turbulent Spark Ignition and Combustion Processes of Ammonia/Hydrogen/Air Mixtures

该研究项目的科学目的是数值模拟零碳燃料（如氢，氨）的层流和湍流火花点火过程。重点是火花能量附近的最小点火能量，在近各向同性湍流在很宽的范围内的流动条件（如湍流强度）和燃烧系统参数（如初始温度，操作压力，混合物成分）。该项目将基于具有不同成分的分层建模概念：详细的数值模拟，基于反应扩散流形的复杂化学-运输相互作用的简化方法，以及基于联合概率密度函数运输方程解的化学-化学相互作用的统计方法。这项建议包含在联合项目（“台湾-NSTC-DFG联合研究项目”）的呼吁中。台湾的合作伙伴（S。Shy）将对零碳燃料（如氢、氨）的点火进行相应的实验研究。

The scientific aim of this research project is to numerically model laminar and turbulent spark ignition processes of zero carbon fuels (e.g. hydrogen, ammonia). The focus is on spark energies near the minimum ignition energy, in near-isotropic turbulence over a wide range of flow conditions (e.g. turbulence intensity) and of combustion system parameters (e.g. initial temperatures, operating pressures, mixture compositions). The project will be based on a hierarchical modeling concept with different ingredients: detailed numerical simulations, a reduction methodology for the complex chemistry-transport interaction based on reaction-diffusion manifolds, and a statistical approach for the turbulence-chemistry interaction based on the solution of the transport equation for the joint probability density function. This proposal is imbedded in the call for joint projects (“Taiwan-NSTC-DFG Joint Research Projects“). The Taiwanese partner (Prof. S. Shy) will perform corresponding experimental investigations of the ignition of zero carbon fuels (e.g. hydrogen, ammonia).
