Electrical features of barrier discharge for microorganism sterilization
Bernát, Jan ; Pfeifer, Václav (referee) ; Bartlová, Milada (advisor)
This thesis deals with barrier discharge through gases from the point of view of electrical attributes and processes that, which are going on in a discharge. The research of a discharge itself is preceded by theoretical discourse about plasma and its attributes and basic information about barrier discharge. Second part deals with processing measured data on an experimental device and is followed by making deduction. The main role is relating instantaneous power P[W] and power drain Pel[W] to supply voltage. Nitrogen and argon gases were used and the experimental measuring device was set in different configuration of gas flow velocity, distance between electrodes, used frequency of a supply voltage and its different level. An algorithm decribing proceding with another data measuring is described in this thesis. The scope of the thesis does not allow for thorough examining of each aspect, which was measured or deduced from data analysis. However the the thesis addresses these aspects and suggests further research.
