Abstract：To study the effect of piezoelectric cells inkjet printing nozzle length on injury factor of cell in the tube.Numerical simula-tion and theoretical analysis were used in this article.With the increase of the nozzle length,the overall pressure and the maximum pres-sure in pipe were increased obviously.And there was no impact on shear stress,but shear stress gradient had decreased with the length of nozzle increasing.This is more conducive to the separation of droplets and decrease the tensile effect of shear stress gradient on cells with the increase of the nozzle length,but it increases the damage of pressure and fatigue,so as to decrease the survival rate of cells.
