ABSTRACT
An important part of an experiment or ongoing process is observation. In many fields of science and production, there is a great need for visual monitoring of the occurring process or its result [Irodov n.d.]. However, the inspection may be difficult or even unattainable due to the closed space in which the process under study takes place. One such example is vortex chambers, which serve to mix various gases and substances under pressure or at high temperatures. These are large chambers of a round or conical shape where everything that takes place inside is hidden from the direct view of the observer due to the need to seal the chamber itself. The operation principle of such chambers is based on the multiple circulations of a substance at high velocity in the cavity of the housing, where various substances can be supplied under pressure [Aronson et al. 2015].
