abstract

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.
