Abstract

The fluid flow in the thermal ink jet transducers is highly dynamic in the sense that at no time during its operation the flow reaches a steady state condition. The transient flow is affected by the inertial and viscous effects. These two effects are reflected through the inertance and resistance parameters of the transducer geometry. In this paper we will present a general background on the inertance and resistance parameters, present a method for calculating these parameters for a given 3D geometry, and briefly outline their role in the ink drop ejection process.
