Simulation test of NACA airfoil used on mining axial-flow fan

Researched the application of NACA(National Advisory Committee for Aeronautics) 0012 airfoil on mining axial-flow fan,using this airfoil designed a mining axial-flow fan,and by computer aided design of Fluent,to simulate the internal flowfield of whole fan,simulated the static stress distribution of impeller and pathlines distribution in flowfield of whole fan,worked out the stress parameter don't change more in whole fan flowfield when the fan reverse,the swirl number increases 0.12,reversal flow quantity takes up 64% in the normal flowquantity,fit the relevant provision of Safety Regulations in Coal Mine of China,demonstrated the applicability of NACA0012 airfoil in mining axial-flow fan design.
