| Description
| - A numerical computation of ultrasonic energy density distribution supported finding of sonoreactor geometry, in which the ultrasonic intensity peaks in a long distance from the horn with the theoretical maximum more than 1000x higher than is the initial intensity at the horn surface [10]. The theoretical prediction has been experimentally proved. However, when developing a sono-electrolyser, it has been found, that a small change from optimised geometry and/or the presence of other material inside the reactor strongly disturbs the %22resonance%22 and decreases the maximal intensity of ultrasound. Though that, an arrangement has been found (by choice of material, size and shape of cell and electrodes) with an immersed electrochemical cell, where the ultrasonic intensity in the vicinity of the working electrode is safely higher than cavitation threshold even with the excitation ultrasonic energy at the horn as slow as 10 W.

- Numerické výpočty rozložení hustoty ultrazvukové energie umožnily najít geometrii sono-reaktoru, ve kterém intenzita ultrazvuku dosahuje maxima ve velké vzdálenosti od povrchu zdroje ultrazvuku (hornu). Teoretické vypočtené maximum je více než 1000x vyšší než výchozí intenzita na povrchu hornu [10]. Teoretická předpověď byla experimentálně potvrzena. Při vývoji sonoreaktoru však bylo zjištěno, že i velmi malá odchylka od optimální geometrie či přítomnost jiného materiálu v reaktoru silně narušuje %22resonanci%22 a snižuje maximální hodnotu intenzity ultrazvuku. Přesto se podařilo najít uspořádání (volbou materiálu, velikosti a tvaru cely a elektrod) se vnořenou elektrochemickou celou, při kterém intenzita ultrazvuku v okolí pracovní elektrody s velkou reservou přesahuje hodnotu kavitačního prahu i v případě, že budící energie dodávaná hornem je pouhých 10 W. Objem elektrolyzéru je asi 100 ml a povrch platinové pracovní elektrody je kolem 150 mm2. (cs)
