Abstract:
      To investigate the characteristics of breakup for liquid jet due to hydrodynamics,the time-dependent axisymmetric equations of motion and continuity were solved by the finite volume algorithm,considering the influence of gravity and surface tension.With Volume of Fluid and Level Set method,the development of instability of interface and jet breakup were captured successfully,the results showed the exponential relations between the breakup length of jet and Re/We0.5,and velocity and pressure distributions were obtained,the effects of jet velocity,diameter and ambient fluid viscosity,density were analyzed finally.
