Effects of Curved Blade Stacking Line on the Aerodynamic Performance of Compressor Cascade

The numerical simulation has been carried out to investigate the three dimensional viscosity flow in the compressor cascades with curved blades of different types of stacking lines.The method of the pseudo compressibility was used and the incompressible Navier Stokes equations were solved.The results show that the performance of curved blade is influenced not only by the end angle, but also by the shape and length of the stacking line.
