Modelling of injection, mixing and combustion in rocket engines under real-gas conditions (C01)

本研究项目的最终目标是开发混合多尺度方法来模拟推进剂组合LOX/H2和LOX/CH4在整个火箭燃烧室中的高压真实气体湍流混合和燃烧过程及其在虚拟演示项目中的应用。在热力学和流体动力学模拟的精度和数值效率方面，将改进在FP2中开发的LES和RANS模拟工具。这些方法将通过多喷油器混合的高分辨率大涡模拟和全燃烧室验证配置的模拟来演示。

Final goal of this research project is the development of hybrid multiscale methods to simulate the high pressure real gas turbulent mixing and combustion processes in an entire rocket combustion chamber for propellant combinations LOX/H2 and LOX/CH4 and their application in the virtual demonstrator project. LES and RANS simulation tools developed in FP2 will be improved regarding accuracy of thermodynamical and fluid dynamical modelling and regarding numerical efficiency. The methods will be demonstrated by highly resolved LES of multiinjector mixing and simulations of full combustor validation configurations.
