Determination of a Stone particle trajectory in the flowing water

Abstract

Trajectory of a stone particle released into the flowing water is determined The length of the particle trajectory, i.e. the duration of sinking and the distance traveled by the released particle, is analyzed in terms of the parameters considered: the initial depth at which the stone particle is released into the flowing water, the particle diameter, the flow velocity and the shape factor.

U ovom radu prikazana je metodologija proračuna trajektorije kamena u tekućoj vodi. Analizirani su faktori koji utiču na dužinu trajektorije, odnosno na vreme tonjenja i domet ispuštenog zrna. To su: početna dubina sa koje se kamen ispušta u vodeni tok da slobodno pada, krupnoća kamena, brzina toka (ambijentalnog fluida) i faktor oblika zrna.
