Parameter Design And Optimal Study Of Mine Centrifugal Fan

Now,it is a trend that the modern information technology is applied to traditional product design. The thesis manages to search a way to increase efficiency of designing mine centrifugal fan, improve design method,reduce design cost under the help of advanced CFD technology. Firstly,the thesis designs initiatively fan under the theoretical design method and gets primary parameter of fan. On the basis of designing mine centrifugal fan,the thesis uses the CFD software——FLUENT to stimulate the designed centrifugal fan in the way of three-dimensional numerical method.In that way,we get performance parameters about the mine centrifugal fan.Through contrastively stimulating many models of centrifugal fan which are made by changing some primary geometrical parameters that effect on fan's performance,such as blade installation angle,blade number,rotate speed,then we can acquire degree that each parameter effects on centrifugal fan's performance. Based on the analyst for the result of stimulation, regarding fan's efficiency as target and making use of two optimal design methods, we improve on parameters which effect on centrifugal fan performance, achieve centrifugal fan best design project at last through computing again and again.
