Simultaneous Measurement of Temperature, Size, and Velocity of Drops in Sprays

Aerometrics, Inc.

Sunnyvale, CA

An instrument which measures temperature, size and velocity of drops in sprays using rainbow refractometry/thermometry

• This laser-based, non-intrusive diagnostic instrument can measure temperature (refractive index) of individual spherical droplets in complex reactive sprays while simultaneously measuring size and velocity
• Applications have included burning droplet streams, swirl-stabilized spray flames, and multi-component non-reactive sprays

• Received orders for $500K worth of equipment in July 1995
• Sold to universities (Carnegie Mellon) for use on spray combustion studies
• Sold to aerospace industry for use in rocket injector studies
• Inquiries from Japan, China, France, and Korea
• Contributed to an expanded new location

• High Speed Research (HSR), Advanced Subsonic Transport (AST), icing and in rocket injector research and gas turbine combustion research
• Prototype rainbow thermometer delivered to Glenn and integrated with existing two component Phase Doppler Particle Analyzer
