A particle generator capable of generating monodisperse aerosol around 0.1 micrometer will be developed. number of particles generated will exceed 10 to the 12 power particles per second. the principle to be explored is fluid energy grinding principle, commonly used to grind bulk solids in chemical… More

A droplet generator capable of producing droplets in the size range of 40 to 400 micrometers will be developed. this droplet generator operates on the principle of liquid jet break-up by mechanical vibration. with this type of generator, the operating parameters can uniquely define the droplet size.… More

In order to evaluate and improve systems and procedures for smoke control aboard ship, safe and effective techniques and equipment for conducting smoke movement tests are needed. this can be done by developing a smoke generator and smoke measuring instrument. the smoke generator will be a hot fluid… More

Failure of air cleaner systems is a major cause of engine failure. a need exists for a detector to indicate when particles are entering the engine. the proposed detector provides a low cost solution to the problem. the proposed project will consist of: 1) designing and fabricating the detector; 2)… More

A laser doppler velocimeter system to measure transient impeller flow fields is proposed. this system, using fiber optics, will measure both tangential and radial components of velocity simultaneously. the hardware and associated software will be specially designed to collect and analyze data from… More

Present vehicle drive train diagnostics usually require test stands and often component removal, making them very inefficient. on-board vehicle testing can dramatically increase the efficiency of diagnositc data collection and provide more realistic, on-line information. this proposal describes the… More
