  cavitations
Research on the method of cavitations resistance in a piezoelectric pump with 3-dimensional mesh structure
      
However, when the pump is working, it produces cavitations and the air bubbles that originate from these will flow out of the pump.
      
Cavitations occurring in the pump will bring out noise and shorten the life of the pump.
      
This paper discusses the flowing process inside a nozzle, especially the formation mechanism of cavitations within the nozzle and puts forward a nozzle flow model, which takes account of the injection conditions and nozzle geometry.
      
The comparisons between the computational and experimental results are performed, which show that the liquid spray characteristics could be more truly demonstrated by considering the existence of the cavitations.
