Abstract
Ventilator, as a fluid machine, is widely used in many areas of national life, he has high efficiency, high flow, small volume and low pressure, etc., in daily life, mining and metallurgical industry and other fields have a wide range of applications. In this regard, efficiency and noise are two important indicators of fans, so for the existing fans, there is a need for a design that optimises the efficiency and noise of axial flow fans.
