Improvement and Simulation of Coal Mine Ventilation Fan Intake Ducts
In order to solve the problem of impeller cracks after installing silencers in the press-in ventilation system,a three-dimensional model of the ventilation system is constructed based on SolidWorks and imported into CFD software to carry out numerical simulation,analyse the main causes of the cracks in the impeller,and improve the geometric dimensions of the intake ducts and the shapes of the silencers;finally,the internal flow field of the ventilation system is analysed and the effectiveness of the improvement is verified.Finally,the internal flow field of the improved ventilation system is analysed to verify the effectiveness of this improvement.
