Steady-state wind field reconstruction for pollutant emission location
To test the ability of concentration weight trajectory (CWT) and residence-time weighted concentration (RTWC) to reconstruct pollutant location with pre-computed wind fields, four virtual releases were simulated over a gas plant geometry using wind profiles based on tower measurements. CWT and RTWC algorithms predicted source locations with useful accuracy when using steady-state wind fields to reconstruct transient virtual releases of only one hour of physical time. The results suggested that coarse, pre-computed wind data may be sufficient to permit computationally efficient location of unknown fugitive sources within complex industrial geometries. This is an abstract of a paper presented at the 105th AWMA Annual Conference and Exhibition (San Antonio, TX 6/19-22/2012).
