Numerical studies in axial compressor cascades using partial deposition model

To predict particle deposition in axial compressor cascades, a new particle deposition was developed. Particle deposition was studied by partial deposition model and entireness deposition model. The calculation results showed the two models have large effect on the deposition at the leading edge. Using part deposition model, the phenomenon of a great deal of particle deposition at the leading edge during very short period disappeared while particle deposition appeared relatively even deposition.
