| Abstract:In order to study the resistance characteristics and influence factors of the most widely used separator with blades in aeroen?
gine，the general structure of the separator with blade was used as a model to identify the characteristics. The structure of blade and orifice
were defined，and the resistance mechanism of these two structures was analyzed. The general resistance algorithm model was established
for the separator with blade，and the accuracy of the model was verified by CFD simulation and test of components and engine. The results
show that under the same rotation and flow rate，the resistance of the blade structure is proportional to the outer diameter and inversely pro?
portional to the inner diameter. The width of blade has no effect on the total resistance of separator with blade. The resistance of orifice
structure is inversely proportional to flow area. The resistances of structure of blade and orifice are both proportional to the working rotation?
al speed，and the higher the working rotational speed，the greater the proportion of the resistance of the blade structure. The proposed resis?
tance algorithm is more efficient，convenient and accurate than the simulation analysis method and the test method. |
