我们提出了一种同时模拟涡轮机械和燃烧室中流动的方法。该方法允许预测燃气轮机的单个部件之间的相互作用。使用两个独立的流动求解器，一个用于涡轮机械，另一个用于燃烧室。流求解器同时执行，每个计算流的一部分，并不断在接口处交换流信息。我们介绍该方法及其验证。然后，我们将该方法应用于真实的发动机几何结构，并模拟压缩机和燃烧室预扩散器之间的相互作用。版权所有 © 2005 ASME
We present an approach to simulate the flow in turbomachinery and combustor simultaneously. This method allows predicting interactions between single components of a gas turbine. Two separate flow solvers, one for the turbomachinery, and one for the combustor is used. The flow solvers are executed simultaneously, each computing a section of the flow, and constantly exchanging flow information at the interfaces. We present the approach and its validation. We then apply the approach to a real engine geometry and simulate the interactions between the compressor and the prediffuser of a combustor.Copyright © 2005 by ASME
