Experimental aero- and thermal investigation for a next generation engine exit module.
Övrigt konferensbidrag, 2019
A unique facility for experimental testing of TRS at engine-realistic flow conditions is currently available at Chalmers' Laboratory of Thermal and Fluids Science and will be used for testing of novel TRS designs for future more efficient aero-engines. The unique design of the facility includes an open test section which permits investigation of the complete TRS assemblies consisting of a TRS and a core exhaust nozzle. The facility is equipped with a 1.5 stage shrouded low-pressure turbine (LPT) providing realistic inflow to the tested TRS.
The main objective at Chalmers is to gain an understanding of the flow mechanism affecting the performance of the LPT-OGV and to validate designs that take advantage of the acquired knowledge. One expected outcome of the project is the most comprehensive aerothermal validation database for TRS designs. For this new measurement methods have been developed and implemented. At the time of writing hotwire and PIV are used to investigate boundary layer development and IR thermography for steady-state heat transfer but further extensive testing is planned within the project. The most up to date results from the test campaign will accompany the already published scientific work in this presentation.
