Originální abstrakt

The quality of atomization is crucial in combustion processes, especially in cases of highly viscous fuels. Twin-fluid atomizers have been developed for atomizing heavy and waste fuels and they have undergone significant development in the last decades. Nevertheless, in order to design an atomizer for a given industrial application, a comparison of different atomizers at similar operating conditions is required. This paper focuses on the description and comparison of two internally mixed twin-fluid atomizers at the same operating regime. The Y-jet and the Inverse-effervescent atomizers were examined. The phase-Doppler analyser was used to measure the velocity and size of droplets in a radial profile in the spray. Data were sorted out into classes with respect to the droplet size and the motion analysis was done for both atomizers.

Český abstrakt

Článek pojednává o porovnání dvou dvou-médiových trysek pomocí Dopplerovského analyzátoru, akterý umožňuje měření rychlostí a velikostí kapek ve sprejích. Naměřená data byly roztříděny do tříd podle velikostí a následně z získaných hodnot byla provedena analýza pohybu kapek ve spreji.
