Research on power consumption characteristics of high viscosity fluid mixing in acoustic resonance mixer
Acoustic resonance hybrid uses mechanical resonance to generate high-acceleration vibrations to promote fluid flow.Its power consumption characteristics play an important role in its design and application.In order to study the power consumption characteristics of the acoustic resonance mixer,a simulation model of the acoustic resonance mixing process was established based on CFD.The force and work power of the wall on the material during the acoustic resonance mixing process of high viscosity fluid were analyzed.The effects of changes in viscosity and vibration parameters on the mixing were explored.The influence of the power consumption characteristics of the acoustic resonance mixer is determined,and the prediction function of the mixing power of the acoustic resonance mixer is established.The research results show that during the mixing process,the instantaneous power of the wall surface working on the liquid phase shows a trend of first decreasing and then stabilizing fluctuations,while the effective power shows a trend of first increasing and then stabilizing fluctuations.This different change trend is caused by the change of the phase difference between the two.The research results show that during the mixing process,the instantaneous power of the wall surface working on the liquid phase shows a trend of first decreasing and then stabilizing fluctuations,while the effective power shows a trend of first increasing and then stabilizing fluctuations.This different changing trend is due to changes in the phase difference.Increasing the amplitude,frequency or low-frequency large amplitude under equal acceleration can increase the instantaneous power and effective power,and reduce the external energy absorbed by the liquid phase to enter the stable flow stage.
