Measurement of the axial dispersion coefficient of powders in a rotating cylinder: dependence on bulk flow properties

the effects of changing roughness on the flow structure in the bends

flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...

Flow Properties of Powders and Bulk Solids

In order to compare and optimize powders regarding flowability and to design powder handling equipment like silos, feeders, and flow promoting devices, it is necessary to know the mechanical properties – the so-called flow properties. In the present paper it is outlined which physical parameters describe the flow properties of a powder or a bulk solid, and how these parameters are determined ex...

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
