Primary breakup modelling with Coupled Level-Set Volume of Fluid (CLSVOF). The atomization of liquid fuel in an aircraft engine plays a key role in the combustion process, affecting the efficiency of the combustion process, emission of pollutants and stability of the system. However it is very difficult to study this process in the high temperature and pressure environment of the aircraft gas turbine system, therefore numerical simulation of this has a key role to play. This project will use a 'Coupled Level Set Volume of Fluid' (CLSVOF) CFD method for unstructured meshes developed in previous projects to simulate the atomization process. Experimental data produced at Loughborough University for the spray produced by a real gas turbine fuel injector under lab conditions will be used to validate the simulation method which will in turn be used to provide further understanding of the physical processes happening in the experiment. The conditions in the 'numerical experiment' can be changed to those in the engine at operating conditions and this will allow investigation of how the trends seen in the lab tests will relate to those seen at engine conditions.

耦合水平集流体体积（CLSVOF）的初级破碎模型。航空发动机液体燃料的雾化在燃烧过程中起着关键作用，影响着燃烧过程的效率、污染物的排放和系统的稳定性。然而在高温高压环境下研究飞机燃气涡轮机系统的这一过程是非常困难的，因此数值模拟对此有着关键的作用。本计画将使用“耦合水平集流体体积”（CLSVOF）计算流体动力学方法，在先前的计画中开发非结构化网格，以模拟雾化过程。拉夫堡大学在实验室条件下对真实的燃气涡轮机喷油器产生的喷雾进行的实验数据将用于验证模拟方法，该方法将反过来用于提供对实验中发生的物理过程的进一步理解。“数值实验”中的条件可以改变为发动机工作条件下的条件，这将允许研究实验室测试中观察到的趋势与发动机条件下观察到的趋势之间的关系。
