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.

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/CH 4的高压真实的气体湍流混合和燃烧过程及其在虚拟演示器项目中的应用。在FP 2中开发的LES和RANS模拟工具将在物理和流体动力学建模的准确性以及数值效率方面得到改进。这些方法将通过多喷嘴混合的高分辨大涡模拟和全燃烧室验证构型的模拟来证明。
