Measurements of solids concentration and axial solids velocity in gas-solid two-phase flows

Investigation on Dynamic Calibration for an Optical-Fiber Solids Concentration Probe in Gas-Solid Two-Phase Flows

This paper presents a review and analysis of the research that has been carried out on dynamic calibration for optical-fiber solids concentration probes. An introduction to the optical-fiber solids concentration probe was given. Different calibration methods of optical-fiber solids concentration probes reported in the literature were reviewed. In addition, a reflection-type optical-fiber solids...

The Vacancy Concentration and Diffusion in Rare Gas Solids H

Using the two-body Mie, Lennard-Jones potentials derived from solid state properties, the vacancy concentration p. and self-diffusion coefficient D are calculated for the rare gas solids. The results are summarised in Tables l-3. Agreement is obtained with the observed D but not with p.. If the usual interpretation is applied, the agreement of I) suggests the absence of many-body forces whereas...
