Environmental Modelling – Wind Model, incl. Gas Reactions

• NOX concentration

• SW wind weak

• NO PHOTOACTIVITY

• NOX concentration

• SW wind weak

• HIGH PHOTOACTIVITY

Prof. Dr. Michael Bruse, ENVI-met.com, Essen

Deposition rate: 0,2 cm/s

It is possible to reduce the concentration of NOX up to 12%.

Self Cleaning (Adsorbed Organics) and Air Cleaning (VOC and NOX)

Simulation Example

Fronts, roofs, walk – used for NO2,O3 destruction;

Average deposition rate 0,4 cm/s => in average 30% decrease of air pollution per

year <=> 100 days of total prohibition of heating and driving (fossil energy)
