An investigation of the generation of acoustic emission from the flow of particulate solids in pipelines
The transport of particulate in a gas flow or pneumatic conveying system 1s widespread in many areas of industry, for example chemical, food processing, cement industries and transportation of pulverised coal in coal-fired power plants. However, a simple and reliable method for monitoring the flow …

The wear of materials in hydraulic transport pipelines
The hydraulic transportation of particulate solids through pipelines results in wear of the pipeline walls. The lifetime of the pipeline is determined by this rate of material loss and is therefore critical to the designer. Due to the small amounts of material lost in in-situ tests, requiring in …

Shear and normal stresses in uniaxial compaction.
… chosen to investigate the uniaxial compaction of particulate solids. Dentritic and cubic sodium chloride were chosen as plastically deforming, dicalcium phosphcte and sugar as fragmentary and styrocell, homopolymer and copolyrinier as non-compactable materials. The uniaxial compaction of the …

Operation of a Tubular Anaerobic Digested on Piggery Waste
… days on pig slurry of 10,,5,.2.5 and 1% Total Solids content. Tube inclination of 16-20 overcame the scumming problems encountered with horizontal tubular digesters. Performance compared favourably with completely mixed digesters, gas yields showing similar variations with operational …

A comparison of the fluidized bed drying technique with conventional methods of drying tablet granulations
… as the suspension and agitation of a bed of particulate solids by a vertically rising stream of gas. Each suspended particle is surrounded by the gas. This relative velocity of the gas and solid particles is high, although the gas velocity itself is relatively low. Heat is transferred by by a …

The flow of particulate bulk solids in an air-assisted gravity conveyor
… to the air-assisted gravity conveying of bulk particulate solids. Aspects of the behaviour of fluidised powder in stationary beds were studied where it seemed possible that observations of such behaviour might be useful in predicting how the same powder would flow in an air-gravity conveyor. As …

Computational fluid dynamics (CFD) modelling of critical velocity for sand transport flow regimes in multiphase pipe bends.
… pipelines could be severely hindered by particulate solids deposit - such as the sand particles that can accompany hydrocarbon production. Knowledge of the flow characteristics of solid particles in fluids when transported in pipelines is important, in order to accurately predict solid …
