The most evasive properties of solid/gas transport, particle, and slip velocities have been determined experimentally using an Auburn Monitor. A High Pressure (150 psig) Coal Flow Test Facility, in which two Auburn Monitors were installed in a vertical limb two feet apart, was used to conduct the coal flow tests. The signals from the two Auburn Monitors were cross-correlated using a commercial correlator. The time delay between the two signals was measured from the cross-correlation function, which in turn yielded the particle and slip velocities. Coal flow tests have been carried out at solid/gas loadings as high as 50 lb of coal/lb of gas. At certain loadings, slip velocities were quite large. The availability of particle and slip velocities permits more complete modeling analysis.
