Simulation Results

Discrete, or Distinct, element modelling, DEM, is used to investigate the effect of particle shape on hopper flowrate. Firstly, simulation results using a model based on spherical particles are validated against solid discharge rates predicted by the modified Beverloo equation. The validated model is then used to investigate the shape effects on discharge rate from a flat bottomed rectangular hopper. Two regular rounded polyhedral particles are studied. The discharge rate varies significantly with particle shape. A reduction on flowrate of up to 49% and 41% is observed for tetrahedral and octahedral particles, respectively. The effects of friction, cohesion, and damping on flowrate are also investigated with DEM.

Illumination Mode

The tilted beam illumination method is used to improve the resolution comparing with the axial illumination mode. Using this advantage, a restoration method of several tilted beam images covering the full azimuthal range was proposed by Saxton, and experimentally examined. To make this technique more reliable it seems that some practical problems still remain. In this report the restoration was attempted and the problems were considered. In our study, four problems were pointed out for the experiment of the restoration. (1) Accurate beam tilt adjustment to fit the incident beam to the coma-free axis for the symmetrical beam tilting over the full azimuthal range. (2) Accurate measurements of the optical parameters which are necessary to design the restoration filter. Even if the spherical aberration coefficient Cs is known with accuracy and the axial astigmatism is sufficiently compensated, at least the defocus value must be measured. (3) Accurate alignment of the tilt-azimuth series images.
