In this thesis, numerical solutions of a 2D stator compressor
cascade at a given inlet Mach number (0.7) and four values of
incidence (49° / , 51° / , 53° / and 55° / ) are obtained. Reynolds averaged,
thin layer, compressible Navier Stokes equations are solved. Different
grid types have been generated. Finite differencing approach and LU
- ADI splitting technique are used. Three block parallel Euler and
Navier Stokes solutions are compared with the experimental results.
Baldwin-Lomax turbulence model is used in the turbulent predictions
and boundary layer comparisons and numerical results are in good
agreement with the experiment.
On the last part of the study, a rotor wake in the inlet flow has
been introduced in the steady and unsteady analyses. The influence
of this wake and the wake location in the inlet flow, to the total force
and pressure is presented. The results have been showed that there
is a relationship between the wake position and the incidence value of
the case.
