Experimental content: A microporous piezoelectric ultrasonic atomization effect test system was built. Working fluids including high-viscosity fluids were selected as atomization objects. The effects of the liquid's surface tension, viscosity, micropore diameter and driving voltage on the piezoelectric micron atomization were measured. The influence of droplet size and atomization flow rate of hole ultrasonic atomization was analyzed, and the changing trend of atomization effect was analyzed.
