Designed for a very broad wavelength range at near normal angle of incidence, two identical wedges can be used to compensate for dispersion and angular deviation. New material is presented on global warming and acid rain, as well as additional coverage on the chemistry of air pollution. The Gaussian plume model is a standard approach for studying the transport of airborne contaminants due to turbulent diffusion and advection by the wind. (2) Continue work on more sophisticated models for risk assessments and to improve or eventually replace the simpler operational model. NET framework. Software for the area air quality control - Petersen & Kade Dispersion calculation for dust, air pollutants, odor and noise and other environmental computing programs according to TA Luft 2002 , VDI 3782 part 1/2/4 , Factor-10-Method , VDI 3783 part 1/2 , VDI 3781 part 1/4 , VDI 2066 and others. (2) A long path (integrating) monitor, the SANOA UV-DOAS, in order to assess average pollutant concentrations along a line as opposed to point monitoring. Whether you’re modeling air dispersion, fires, or explosions you need a standards-based, integrated platform to build on. However, models have rarely offered variables that account for the dispersion environment close to the source (e. The FSW-6000/7000 Series are thermal flow switch monitors designed to monitor flow status and also used to detect level of liquids, air and gas. About Bentley Bentley Systems is the leading global provider of software solutions to engineers, architects, geospatial professionals, constructors, and owner-operators for the design, construction, and operations of infrastructure, including public works, utilities, industrial plants, and digital cities.

Among many potential applications, simFlow capabilities can be used to: estimate efficiency of chemical reactors; model spray phenomena and coal combustion. It can be used to model non-buoyant point, line and area sources.
