Abstract Details

2011, MS, University of Cincinnati, Engineering and Applied Science: Aerospace Engineering.
An analysis of the MIT counter-rotating aspirated compressor (CRAC) has been conducted using two different 3D viscid turbulent unsteady solvers. The Turbo phase-lag time accurate and the Numeca FineTurbo Non-Linear Harmonic (NLH) methods were utilized to gain an understanding of the flow field. Grid dependency studies and comparisons with experimental data were conducted where appropriate. Speedline simulations were conducted to better understand the off-design performance of this compressor stage. Both simulation methods show good agreement with the experimental data. The best agreement is found between the FineTurbo simulation when using iso-thermal boundary conditions. Comparisons of simulations with and without aspiration illustrate the importance of aspiration on the stage performance. Unsteady analysis of the flow field is presented to show the details of the blade row interactions. A detailed analysis of the aspiration slot and plenum was also performed.
