Prediction of Optimal Operating Conditions for Dense-Phase Pneumatic Conveying Systems

The fluidised dense-phase conveying of powders and low-velocity slug-flow of granular bulk solids are the most common and popular modes of dense-phase used in industry. However, the accurate prediction of conveying performance still is not possible from first principles and relies heavily on empiricism. The main aim of this project is to develop the necessary understanding, databases, duidelincs and models for the purpose of predicting accurate optimal operating conditions for the fwo modes of dense-phase. This Annual Progress Report summarises the project objectives, research progress and major achievements for the period September 1998 to November 1999, and includes objectives for the second year of the project.
