该项目的目标是建立一个实验数据库，记录燃气涡轮发动机喷油器喷雾与燃烧室穹顶内旋转气流相互作用时的行为，并对当前预测燃油喷雾行为的分析技术的有效性进行评估。重点是使用与目前先进飞机燃气涡轮发动机中使用的部件非常相似的喷射器/旋流器组件获取数据，在非常模拟或非常接近实际燃烧室中开发的条件下进行测试，并进行控制良好的实验工作，其中包括使用低风险实验和需要使用最先进诊断仪器的实验的组合。数据的分析将使用现有的teach型代码进行，该代码采用对湍流连续流场中分散相运动的随机分析。
The objectives of this program are to establish an experimental data base documenting the behavior of gas turbine engine fuel injector sprays as the spray interacts with the swirling gas flow existing in the combustor dome, and to conduct an assessment of the validity of current analytical techniques for predicting fuel spray behavior. Emphasis is placed on the acquisition of data using injector/swirler components which closely resemble components currently in use in advanced aircraft gas turbine engines, conducting tests under conditions that closely simulate or closely approximate those developed in actual combustors, and conducting a well-controlled experimental effort which will comprise using a combination of low-risk experiments and experiments requiring the use of state-of-the-art diagnostic instrumentation. Analysis of the data is to be conducted using an existing, TEACH-type code which employs a stochastic analysis of the motion of the dispersed phase in the turbulent continuum flow field.
