摘要: The observed cyclic operation of a riser near choking was calculated using computational fluid-dynamic model used previously to predict its flow regimes. An approximate analytical expression for the maximum carrying capacity Geldart A, B and C particles developed compared data in literature. In new theory, an unknown parameter is pseudosonic velocity particles. To estimate this quantity, granular temperatures were measured from literature regime (2% 20% solid volume fraction), turbulent intensity approximately 0.5, agreement with theory. theoretical value involves ratio particle viscosity conductivity.
