Analysis of the Dynamic Behavior of Solid Particles in Compressors

Abstract : The three-dimensional equations of motion of solid particles entrained by compressible gas flow in a rotating cascade are solved for the case of particles moving through a compressor guide vane followed by a compressor stage. The solution considers the change in particles dynamic characteristics due to impacts with surrounding walls. The dynamic behavior of the particles for different particulate flow parameters are investigated. Observations concerning compressor blades erosion damage are also discussed. (Author)
