Analysis of 3D Numerical Simulation for an Airfoil Probe in a Compressor

Abstract

A numerical simulation has been done using CFX11.0 to study the effect of an airfoil probe installed at the leading edge of first stage stator in a compressor. Combination of structured and unstructured grids has been used during the calculation. Result shows that blade loading with and without probe is obviously different at 50% height of blade, while the effect at 20% and 80% height of blade is not obvious. The result has proved that probe indeed has an effect on performance of a compressor, and especially on a compressor with a high speed, high pressure ratio .A corresponding test will be done to validate the result and for a further study.
