In order to investigate the flow field characteristics of the typical stabilizer of afterburner under the inlet conditions similar to the actual incoming flow, the non-uniform inlet conditions (including non-uniform velocity and non-uniform cosine rotation angle) were given through the user-defined function. Then the cold flow field of the typical stabilizer of an integrated model was numerically simulated using the Reynolds average method. The flow field, total pressure loss and flow resistance loss coefficient were studied. The numerical results showed that: 1) The recirculation zone of the cavity on central cone wall increased gradually with the increase of the velocity non-uniformity, while the recirculation zone of stabilizer decreased. With the increase of non-uniform cosine rotation angle, the reflux flow of the cavity of central cone decreased inward, while the reflux flow of stabilizer increased radially inward. 2) When the cosine rotation angle was greater than 15 °, the flow rectification performance of the stabilizer was significantly weakened, and the flow separation on the pressure surface formed a reflux zone, which increased the flow loss of afterburner. 3) The total pressure loss and flow resistance loss coefficient increased with the increase of velocity nonuniformity and cosine rotation angle nonuniformity. In addition, the cosine rotation angle could increase the velocity variation rate.
