The effects of operational parameters (including flow rate and agitator rotation rate), material flow properties (characterized by the angle of repose), and design parameters (including the number of blades and blade angle) on solid hold-up, mean residence time (MRT) and relative variance of residence time were investigated.
Material properties are characterized by the secondary-emission ratio, defined as the number of secondary electrons emitted per primary electron.
The material properties were characterized and microstructural analysis was carried out.
Bulk and surface chemistry as well as other material properties were characterized.
Material properties were characterized based on parameterization of the stress-strain curves using a simple and novel mathematical expression.
The microstructure and material properties were characterized using X-ray diffraction, scanning electron microscopy, the Vickers hardness test, and wear and corrosion testing.
The great disadvantage of the classical DEM, such as the particle flow code PFC (material properties are characterized by spring stiffness), is to feed them with material properties provided from laboratory tests (Young's moduli, Poisson's ratio, etc)., which are not quite consistent with stiffnesses of springs, the PFC requires.
While simulations were based on data collected at Borden, models were exercised beyond the geometric and material properties that characterize the site.
The material properties that characterize the interface, namely the shear stiffness, the cohesion and the mode-II fracture energy, are evaluated with the objective of simulating the experimental results obtained from double lap shear tests on glass GFRP bonded joints.
A number of methods have been developed to determine the relaxation modulus, which is a fundamental material property that characterizes the rheological behavior of viscoelastic materials.
