The Waterjet Laboratory is located on the first floor of Mechanical Engineering Center. The laboratory is equipped with the industrial scale facilities for waterjet machining and cleaning applications, as well as instrumentation for the investigation of the water and abrasive waterjets, jetworkpiece interaction and topography of the surfaces generated as the result of the jet-substrate interaction.

The main current project involves formation of the super-high speed water slugs by direct energy injection into the water. This technology will enable us to eliminate the use of pumps for water compression. Another project is concerned with use of ice-air jets for  surface cleaning. This jet will provide an effective tool for decontamination of electronic and precision machining parts, removal of graffiti, cleaning food products, etc.

Our results to date include methods for eye surgery (US Patent 5964775), method of damage free precision cleaning, algorithm of optimization of cleaning technology, advanced nozzle geometry and scientific communities. The results of the work were exhibited at the Capitol Hill. Ten PhD dissertations and 16 MS theses were defended as the result of laboratory research. The work of the waterjet laboratory is sponsored by National Science Foundation, the Center for  Microfluidics and the Center for Multilifecyle Engineering of NJIT.

The laboratory pioneered the following innovations: measurement of jet velocity; jet visualization; mechanism of material removal by impinging jet; mathematical model of waterjet cleaning; waterjet based precision cleaning; waterjet based polishing; formation and applications of ice-fluid jets; technology for in-situ cleaning of chemical reactors; eye surgery.
