Investigation and application of high accuracy schemes in numerical simulation of turbine flow field

PAUSMPW program and PMAUSM+up program based on improved MAUSM+up scheme are developed by the original three-dimensional viscous flow calculation program PTVD through studying high accuracy schemes, such as TVD, AUSM family schemes and son on. These programs are used for numerical calculation of the NASA high speed test and MARKII type blade 5411 test, and their viscous flow fields are analyzed. Compared to the three calculation results by the original program, the PMAUSM+up program and CFX software, higher accuracy and reliability of the PMAUSM+up program are proved.
