In order to further explore more details of the fluid field aerodynamic force of local fan in coal mine,this paper takes JK25 series local fan as the research object,and analyzes the distribution law of aerodynamic force in the fluid field under different speed and different wind pressure based on the modeling of its blade parts.The aerodynamic distribution of blade surface was analyzed and compared.At the same time,the fan fluid field flow diagram is used to analyze the changing law of fluid flow in the fluid field under different parameters,so as to preliminarily analyze the direction of optimization of JK25 series local fan.
