摘要：A two dimensional stability analysis is introduced to study the characteristics of rotating stall in a wide radial vaneless diffuser. The prediction of the critical flow angle and propagation velocity given by a linear stability model are given and compared to existing results in literatures. The growth rate of the different competitive mode are used do try to determinate the dominant stall mode. The equations used for a weakly nonlinear analysis which focusing on a small distance from the critical condition are then proposed.
