SINOPSIS

This paper summarizes the classifications of flow regimes, demarcations between flow regimes and equations describing each flow regime for fluidized and nonfluidized gas-solid flow in a standpipe. Effects of gas compression and aeration on behaviour of mixture flow (e.g. void profile and pressure drop) are studied. Additionally, two governing equations are suggested to simulate the flow of gas-solid mixtures through an orifice or a valve, which show good agreements with experimental data.
