Micronozzle Atomizer

Oregon State University, Microproducts Breakthrough Institute, Oregon, United States

TECHNOLOGY SUMMARY

Micronozzle atomizers constructed using a multi-layer architecture with air-blast, high pressure, and drop-on-demand modes of operation. Small droplet sizes and tight size distribution have been demonstrated (<15 micrometer D32, <25 micrometer Dv90). Applications range from fuel injection to spray painting to thin film deposition. Patents pending.

Primary Application Area: Automotive & Transportation

GOVT/EXTERNAL FUNDING SOURCES

Government Funding/Support to Date: The State of Oregon through the Oregon Nanoscience and Microtechnologies Institute (ONAMI) provided funding for development of a MEMS fuel injector project with Northwest UAV Propulsion Systems (NWUAV). During this project the micronozzle atomizer concept was developed and tested. Small fuel droplet sizes and tight size distributions (&lt;15 micrometer D32 with &lt;25 micrometer Dv90) were demonstrated at low operating pressures (&lt;15 psi). Engine testing showed improvements in fuel efficiency and reductions in emissions. A change in business focus at NWUAV suspended further development.
