Description
  • Pevnost kapalinových můstků v náhodně nasypaných částicových materiálech byla analyzována pomocí počítačové simulace. Byl implementován algoritmus pro popis pohybujících se fázových rozhraní a určen tvar kapalinových můstků v rovnovážném stavu. Byly vypočítány kapilární síly působící na jednotlivé částice a celková soudržná kapilární síla částicového materiálu. (cs)
  • The strength of capillary bridges in randomly packed granular media was analyzed by means of computer simulations. A novel simulation method, based on the tracking of moving interfaces, has been implemented and used for determining the equilibrium shape of capillary bridges in a granular medium under a range of liquid saturations and solid-phase geometry. The net force acting on each grain due to the capillary bridges was evaluated, as well as the aggregate force acting between two wet granular media during their separation in the normal directions. The simulation results are consistent with previous experimental observations and reveal interesting phenomena such as the existence of a maximum in the tensile strength of a wet granular medium as function of liquid saturation.
