Mathematical modelling of sedimentation processes in a centrifuge

Separation Science and Technology, 1991
Abstract A mathematical model describing concentration-dependent sedimentation in a centrifuge is suggested. The present model contains the already existing models as partial cases, and it has some advantages. An interactive system for numerical solution of the model equations was created.

Separation in a centrifuge-model

Applied Scientific Research, 1961
The gas centrifuges which were used for isotope separation 1,2) have cylindrical rotors. In consequence of the equality of the relaxation times for diffusion and gas motion, and taking into account the pressure-dependence of the diffusion constant, the time-dependent equation for a cylindrical centrifuge is rather complicated 3).

Centrifuges in modelling: principles and scale effects

2010
Centrifuge model testing represents a major tool available to the geotechnical engineer since it enables the study and analysis of design problems by using geotechnical materials. A centrifuge is essentially a sophisticated load frame on which soil samples can be tested.

Modeling liquefaction in centrifuges

2018
In the past twenty years or so, numerous investigations on the centrifuge have been carried out to reproduce seismically induced liquefaction phenomena and to study their effects on the stability of such earth structures as homogeneous or stratified level ground, slopes, embankments, water front structures, sheet pile walls, buried structures, etc.

Centrifuge modelling of laccolith intrusion

Journal of Structural Geology, 1987
Abstract Laccolith intrusion has been investigated by centrifuge modelling. Silicone putty, representing magma with Bingham rheology, is intruded by overburden pressure through a circular conduit into a stack of paraffin wax layers, which represent sedimentary strata.

Modeling Solute Transport by Centrifugation

Journal of Environmental Engineering, 1989
Measurements of physical and chemical solute transport properties of soil/waste systems are necessary to predict pollutant migration in soils. The sorption distribution coefficient is most often determined in the laboratory by performing column studies or batch equilibrium tests. Both of these methods suffer from disadvantages.

Centrifuge Modeling of Buried Pipelines

Advancing Mitigation Technologies and Disaster Response for Lifeline Systems, 2003
Fault crossing, lateral spreads and other types of permanent ground deformation (PGD) are arguably the most severe seismic hazards for continuous buried pipelines. Current analysis and design procedures, to a great extent, are based upon Finite Element (FE) modeling.

Sectional Modeling of a Centrifugal Compressor

4th International Pipeline Conference, Parts A and B, 2002
The prediction of compressor performance using steady-state methods has had limited success for multistage configurations. Accepted limitations of the computational methods such as streamline curvature effects have been ignored because of a more dominant issue of the interface between the rotating and stationary components and the change in pitch ...
