| 英文摘要 | Deeply research on management and application ofhot streak is an important way to breakthrough technique ob- stacle of aero engine hot components. Numerical method is a useful instrument to investigate the correlative problems. Firstly the paper developed independently three dimensional unsteady parallel computational code-MpiTurbo based on Fortran 90 and MPI at Linux operating system. Then unsteady numerical simulation was carried out to investigate impacts of the factors, which included circumferential locations of hot streak and clocking positions ofblade rows, on the thermal environment of a l+1 counter-rotating turbine. The results clear- ly indicated that clocking positions of hot streak/blade row and blade row/blade row had great influence on the time-averaged temperature distribution of the third blade row. Therefore, it can be effective for improving thermal environment of turbine to optimize blade parameters and clocking positions. Lastly film cooling layout was de- signed by the repetitious steady simulation based on source term method. And the flow structure detail was given by the unsteady simulation. |
