Computational PDEs Unit: Atmospheric dispersion
Atmospheric dispersion
(Back to the CPDE Unit Home Page)
Power station plumes are concentrated sources of Nox emissions, and the
photochemical reactions of this Nox with polluted air leads to the generation
of ozone at large distances downwind from the source. A reduced
atmospheric diffusion
equation is used to model the process, typically using 10 chemical species
and 8
coupled PDEs. This large and complex multi-scale model provides a stringent
test for the SPRINT2D software, with very
promising results to date (see [37]
, [39]).
The figure below shows some example results for the ozone level in a power
station plume.
