摘要：

Pressure drop and choking were calculated for dense-phase vertical pneumatic conveying of solids using a model employing two continuity and two momentum equations. The relative equation of motion studied has been previously derived using the methods of non-equilibrium thermodynamics. The calculated pressure drops and choking velocities were found to be in a good agreement with IGT high-pressure lift-line experiments. To compare calculations with data, it was necessary to assume an effective particle size and an inlet void fraction which were not measured. Uncertainties in drag correlations for various flow regimes do not at present permit an equally good mathematical description of fast fluidization. © 1979.
