New technologies to solve environmental problems are in demand nowadays existing methods cannot always be used because they are too expensive, have unwanted byproducts or simply don't work a new approach is to create active species in situ so transport losses can be avoided pulsed corona discharges is such. Visualizations and measurements by particle imaging velocimetry are conducted in a wind tunnel in order to determine the influence of a dc corona discharge established between a wire and a plate collecting electrode on the properties of an airflow around a flat plate results show that the kinetic energy induced by the.
In this thesis, a new two-dimensional numerical solver is presented for the dynamic simulation of the trichel pulse regime of negative corona discharge in point-plane con- guration the goal of this thesis is to simulate the corona discharge phenomenon and to improve existing models so that the results have an acceptable.
