Abstract:
Micro-scale jetting devices are used in a variety of applications, from ink
jet printers to microelectronics manufacturing, biomedical procedures and
equipment (e.g., dye-assisted laser surgery), medical diagnostics
manufacturing, micro-optics manufacturing, IC thermal management and
dispensing small amounts of chemicals in neuroscience research.
In this talk I will describe recent research directed at developing a numerical methods for modeling these devices. I will begin with a discussion of the physical processes which characterize micro-scale jetting, and which make them difficult to model; follow with a general description of a numerical +method I have developed - in collaboration with others - with which one can modeling the entire jetting process; from the application of a time dependent pressure or velocity pulse at the inflow boundary of the nozzle, through the formation of the lead and satellite droplets, to the eventual coalescence of some or all of the satellite droplets; and end with an overview of some of the
