This SBIR Phase II project is to develop a simple and                      robust on-line technique for measurement of solids loading and                  gas flow rate of gas-solid mixtures.  The technique employs an                  extended throat venturimeter for which the pressure drop across                 the throat and the pressure recovery across the diffuser are                    measured.  The research includes experimental testing of such a                 venturimeter for air at ambient conditions over a range of gas                  velocities, solids loadings, and particle sizes.  Numerical                     modelling of this two-phase flow will provide a framework for                   predicting the performance of the device and extending its                      operation to different conditions.                                                   A simple, robust device of the type being developed is                     needed for on-line monitoring and control of gas-solids                         processes, especially under conditions of high temperatures,                    high pressures, and high solids concentrations.  The device may                 find use in any number of coal or minerals processing                           applications.
