| Abstract | This thesis investigates the secondary flow field of a prototype and a model jet engine test facility. The accurate prediction of the test facilities entrained or secondary air flow as a function of engine performance characteristics, and test facility geometry, is necessary to ensure adequate cooling air flow without significant induced thrust measurement error. The induced thrust measurement errors of concern are flow field effects such as support stand drag, as opposed to instrumentation errors.
The experiment began with the measurement of flow field velocities in a full scale engine test facility. A model of this test cell was then constructed and similarity demonstrated. Finally, the geometry of the model cell was varied and secondary flow changes were observed.
The results of this testing are in good agreement with similar testing carried out elsewhere. The functional relationship developed in the model tests, expressing the entrainment ratio as a function of engine and test cell parameters is in agreement with the results of the prototype tests. |
