Optimisation Analysis of Silent Blade Structure of Ventilator Based on FLUENT
Aiming at the shortcomings of mine counter-rotating ventilator,which is noisy during operation and affects the safety of use,a variety of blade structure optimisation schemes are put forward,and the operating characteristics of the fan under different blade structures are simulated using FLUENT simulation and analysis software,and the optimal blade structure is determined.According to the simulation analysis,the optimisation scheme of increasing sawtooth notch on the inner side of the blade and increasing the transition of circular arc section on the outer side of the fan can reduce the operating noise of the fan by 14.9％during the working time,which effectively solves the shortcoming of the counter-rotating ventilator's high noise during the working time,and enhances the ventilation environment of the mine.
