Simulation of micro discharges for the optimization of energy requirements for removal of NO/sub x/ from exhaust gases

Experimental and theoretical investigations to remove NO/sub x/ from oxygen rich engine exhaust gases using dielectric barrier discharges are conducted in our laboratory. To explain experimental results in different reactor geometries, a two-dimensional fluid model using an unstructured grid was implemented for the simulation of transient microdischarges. As an example, simulation results of simultaneously occurring microdischarges in a packed bed reactor are presented in this paper.
