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发展混合多尺度方法来模拟整个火箭燃烧室中推进剂组合LOX/H2和LOX/CH4的高压真实气体湍流混合和燃烧过程，并将其应用于虚拟演示项目。FP2开发的LES和RANS仿真工具将提高热力学和流体动力学建模的精度和数值效率。这些方法将通过多喷油器混合的高分辨率LES和全燃烧室验证配置的模拟来验证。

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.
