Due to the recent increase of computational power, the numerical investigation of the flow in gas turbine rim cavities has become possible. Recent investigations have simulated the flow phenomena which commonly occur in gas turbine rim cavities, with special attention on hot gas ingestion. A further focus has been the feasibility of numerical investigations in an engine design process chain. The industrial design timeschedule is limited and so the associated numerical simulations must not be time intensive. As a consequence, the use of 1D models is preferred in most engine design processes. The intention of this paper is to link the 3D-CFD more closely to the engine design process by use of simplified models. Recommendations are given on how to build a rim cavity model which satisfies the requirements of the engine design process to predict the ingestion of hot gas.
