Abstract

Miniature tubular pumps are used to emit droplets from ink-jet matrix heads. This paper deals with the simulation of the behaviour of a viscous and compressible liquid in such pumps. The response of the liquid in the frequency and time domain is analysed.

An approximate method is given to determine the droplet speed and size.
