cze Abstract:
[cze][eng] V článku jsou prezentovány výsledky gravitačního usazování modelové suspenze. Experimenty se uskutečnily pro dvě konfigurace. V prvním případě se jednalo o přirozenou gravitační sedimentaci, ve druhém byly použity ultrazvukové pulzace o frekvenci 20 kHz. Byly použity tři kaolinové suspenze o objemové koncentraci 3,8 7,6 a 11,45. Nebyl pozorován výrazný vliv ultrazvukových suspenzí na sedimentaci.The paper presents results of a gravity settling of a model suspension. Experiments have been carried out for two configurations. The first experiment involved natural gravity settling; in the second case the ultrasound pulsations were introduced. Ultrasound field was provided by 20 kHz horn acting through a wall of settling vessel. Three kaolin suspensions of volume concentrations 3.8; 7.6; 11.4 % were used. It has been found that there is no significant influence of ultrasound pulsations on suspension settling.
