摘要
以矿用外置单电机对旋风机为研究对象,利用FLUENT软件研究变叶片数对其气动性能的影响。结果表明:对旋风机的全压和声功率级随着前后级叶轮叶片数的增加而增大。二级叶轮的整体涡量强度和声功率级比一级叶轮大。
The contra-rotating fan with external single-motor as the research object, the effect of variable blades number on the aerodynamic performance of contra-rotating fan was studied by FLUENT software. The results show that the total pressure and sound power level increase with the number of impeller blades in the front and rear impeller. The overall vortices intensity and sound power level of the secondary impeller are larger than the primary impeller.
