N2 - In aircraft oil cooling system, axial fan has been applied due to its characteristics of high rotation speed and pressure rise, as well as small flow rate and small volume. In this article, a modified variable circulation method for the aerodynamic design of axial fan with inlet guide vanes (IGVs) is newly developed. The design of aviation axial fan with advanced airfoil is performed based on a simplified three-dimensional (3D) flow theory. The effects of several different control parameters such as prewhirl parameters i.e. −0.75, −0.65, −0.55 and −0.45, circulation indexes i.e. 0.4, 0.45, 0.5, and number of IGVs and rotor blades i.e. R19S17, R17S15 and R15S13 on the fan performance are numerically analyzed in a systematic manner. The optimization design of axial fan with IGVs is proposed. Numerical study results indicate that the larger the prewhirl parameter and variable circulation index, the higher pressure rise and the wider effective working range of fan. The more the blade number, the higher pressure rise of fan, while the efficiency is normally kept the same. The effect mechanisms of above parameters on the fan performance are revealed. The current work can provide reference for the optimal design of advanced aviation axial fan.
