Coarse-grained particles conveying along a pipe bed
Vlasák, Pavel ; Chára, Zdeněk ; Konfršt, Jiří ; Kysela, Bohuš
The paper describes the results of a flow visualisation of model coarse-grained fully stratified particle-water mixtures. Investigation was focussed on study of the particle behaviour and carrier liquid and conveyed particles local velocities. Glass balls and washed graded pebble gravel of mean diameter of 6 mm were conveyed by water in a horizontal smooth pipe loop with a transparent pipe viewing section of inner diameter 40 mm. Particle movement along the pipe invert and particulate stationary bed, created by two layers of spherical particles of the same size as the conveyed particles, was studied. The effect of stationary bed on local velocity values of the carrier liquid and conveyed particles were determined. It was conducted that the maximum liquid velocity is significantly shifted from pipe centre to a higher position in the flow pattern with stationary bed.
Visualization of the digital model outputs of the South Moravian Lignite Coalfield in GIS
Kajzar, Vlastimil
In this contribution, possibilities of transfer the data outputs into common GIS formats of the spatial data, are presented. Both vector geofeatures and created spatial models can be transferred using the conversion algorithms. Output data transformation into the GIS data enables multi-user using of the data. In addition, the obtained data can be further processed and analysed. It is also possible to make compositions of the map outputs, which is often needed for classical geological evidence. This contribution deals also with the design of these map outputs.
