Lattice Boltzmann Method (LBM) has recently gained great attention in the flow field modelling, especially in complex medium. One great advantage is the method of handling complex geometries and obstacles in a straight forward particle collision method. The proposed work is to apply a developed and validated Lattice Boltzmann model for incompressible turbulent fluid flows to a subsonic axial compressor with Reynold's number 300,000. The scheme's stability and its performance at higher Reynold's number were investigated for its validity especially at critical flow regimes in regard to the combined LBM Smagorinsky Large Eddy Simulation (LBMLES) Turbulence model. The developed LBM model is applied to investigate the flow inside a subsonic axial compressor, innovatively, this is the first time to be achieved in literature using LBM. Worth to mention, the benefit from LBM's particle-obstacle collision treatment was gained to catch the interaction of fluid with moving rotor and fixed stator blades. Achieved without the need of dynamic grid or moving frames with interfaces as in conventional computational methods in turbomachinery. Finally, the flow field was visualized, investigated and the available turbomachinery parameters were studied for different operating conditions. The error with the available experimental data from the study case is also discussed fairly.
