Numerical Simulation Study on Noise Reduction of a Ventilator
In order to solve the problem that the ventilator has a big noise affecting the operators in actual operation,the purpose of noise reduction is realised on the basis of ensuring the performance indexes such as ventilation efficiency and static pressure.Taking a certain type of centrifugal ventilator as an example,on the basis of constructing numerical simulation simulation model and grid division,etc.,the ventilation efficiency and static pressure corresponding to different improved blades are compared;finally,the noise of the ventilator is predicted after the improvement of the blades,which achieves the expected effect.
