ABSTRACT:
A consistent back pressure formulation is introduced into ink-jet simulation models and algorithms to solve an instability problem that occurs as the head of an ink droplet reaches the end of the solution domain during simulation. The consistent back pressure formulation is obtained in a way that is consistent with the idea of interface smearing. Formulas for calculating the pressure boundary condition on quadrilateral grids are disclosed. An ink-jet simulation example is given to demonstrate the improved models and algorithms.
