Abstract

Microjets can be applied to a variety of areas such as spacecraft propulsion, mass spectroscopy, and biomedical devices. The purpose of this MQP was to design and build diagnostics that effectively characterize a microjet produced from electrospray (ES), flow focusing (FF) and electro-flow focusing (EFF). These techniques produce a fine spray of droplets on the order of microns in diameter. Stable FF was achieved but only for a short duration. There was no stable ES or EFF due to voltage constraints and stability issues. A motion control system for diagnostic testing was developed but not implemented due to these issues. Future work includes redesigning the flow delivery system to resolve the stability problems and further developing the diagnostic equipment.
