After presenting the mathematical description of dynamic fluid for 2-phase flow, numerical simulations are launched to reveal the characteristics of droplet generation and key factors are discussed.
In this paper, the following will be presented: mathematical modeling of 2-phase flow for jet-dispensing, numerical simulations on droplet generation with finite volume solver, experiments and discussions on its feasibility for ink marking of defective dies.
With compensated pressure changing from 10 to 30 kPa, the radii of ink droplets falls on the interval of [0.247, 0.448] (mm) and corresponding jetting velocities are on [0.729, 1.213] (m/s) , which coincide with simulation results in Table 1.
Compensating pressure facilitates the pitch-off of droplet, as observed in CFD simulation, the breakup of droplets shows good response with the pressure descent (or negative edge) on nozzle inlet, which is defined as a periodical pressure boundary condition.
