Annihilation Radiation Gauge for Relative Density and Multiphase Fluid Monitoring

CO-OPERATION between fluid dynamic and neural models USING FUZZY DATA FUSION for monitoring multiphase flows

The knowledge and the forecast of the parameters which rule the down flow models in oil extraction and transport are today of paramount importance. In particular the extracted oil is mixed with water and gas in rates, which differ not only from different wells, but also on the same well during its life. The main problems involved with the measurement of the flow rates are: well exhaustion, crit...

Front Tracking for Multiphase Fluid Mixing

In this paper, we present a two fluid mixing model based on hyperbolic equations having complete state variables (velocity, pressure, temperature) for each fluid. The numerical algorithm is an extension of a front tracking method from microdynamics to macrodynamics. The numerical results are validated by comparison to the incompressible limit.

Investigations of Positron Annihilation Radiation

By combining OSSE, SMM and TGRS observations of the galactic center region, Purcell et al. (1997) and Cheng et al. (1997) produced the first maps of galactic positron annihilation. That data-set has been augmented with additional data, both recent and archival, and re-analyzed to improve the spectral fitting. The improved spectral fitting has enabled the first maps of positronium continuum emis...
