Institute of Particle Process Engineering

Aerosol Technology

Prof. Dr.-Ing. Sergiy Antonyuk

The course includes the physical principles and correlations of dust removal principles as well as corresponding dust measuring devices for their quantification. This includes the implementation of the active principles in suitable technical equipment and equipment (e.g. inertial separators, electrical separators, filtering separators).

Against the current background of the Covid-19 pandemic, the spread of potentially virus-containing human aerosols, their properties, dispersion in rooms and separation in respiratory masks and room air filters are discussed in particular. The dust measuring devices for online and offline measurement of dusts and aerosols must be adapted to the characteristic properties of the dusts and aerosols potentially containing viruses.
The reproducible generation of dusts and aerosols with known properties is also necessary in order to further quantify the technical equipment and equipment with the dust measuring devices. Both will be discussed in detail during the course. During the course, practical work will take place in a group in the Aerosollaboratorium of the Chair of MVT.
