There is a research and process control need for a ruggedized nonintrusive instrument for obtaining absolute size and number density distributions in large-scale combustion systems. such uses can be met by developing a hybrid optical probe comprised of a durable optical system mounted within a… More

Research and development programs for the use of coal-based fuels are currently being pursued by the government, engine manufacturers, and by other research laboratories. there isa strong interest in the development of coal/slurry based diesel engines for locomotive and peak power generation. spray… More

Real time, on-line particle contamination sensors for microelectronic manufacturing in process equipment environments have the potential to improve chip yields through improved process control. current microelectronic manufacturing monitors are limited to low efficiency sampling rates and general… More

Low cost, remote sensing of particle-laden process streams requires continuing instrumentation development to meet the the needs of fossil energy and other industrial applicationsparticulate emissions control which is consistent with process optimization is highly dependent on the entering particle… More

Non-intrusive, on-line sensors of molten metal atomization have the potential to improve powder yields through improvedprocess control. the prediction and control of powdered metal production processes are largely based on operator experience. the complex relations between the operating variables… More

Magnetohydrodynamics (mhd) is a potentially viable technology for advanced and efficient utilization of coal. as with any coal conversion technology, one of the primary requirements is efficient and effective emissions control for ash and other effluents. to enhance understanding of the physics of… More

The objective of this project is to develop a monitor which can evaluate the velocity, size, concentration, and spatial distribution of Weather Generated Particulates (WGP), including sand, ice, etc., under ground-based simulation conditions. Specific instrumentation requirements include the… More

Hydrocyclones have been used for liquid/liquid separation and for degassing liquids for more than forty years and may utimately be the unit of operation of choice for oil/water separation on offshore platforms and on the ocean seabed because of their compactness and simplicity of operation. however,… More

Rapid, on-line characterization of water vapor content and/or condensed-phase (liquid or ice) mass loading is required to measure the total moisture content of flows in ducts from 0.30m to 4.6m in diameter over a range of flow conditions. A successful proposal must address one or more of the flow… More
