Evaluation of an inverse modelling methodology for the prediction of a stationary point pollutant source in complex urban environments
by George C. Efthimiou, Ivan V. Kovalets, Christos D. Argyropoulos, Alexandros Venetsanos, Spyros Andronopoulos and Konstantinos E. Kakosimos
Abstract:
The estimation of a hazardous contaminant unknown source characteristics (i.e., rate and location) in a complex urban environment using efficient inverse modelling techniques is a challenging problem that involves advanced computational fluid dynamics combined with appropriate mathematical algorithms. In this paper we further assess our recently proposed inverse source term estimation method (Efthimiou et al., 2017, Atmos. Environ., 170, 118–129) by applying it in two wind tunnel experiments simulating atmospheric flow and tracer dispersion following a stationary release in realistic urban settings, namely Michelstadt and Complex Urban Terrain Experiment (CUTE). The method appears to be robust and to predict with encouraging accuracy the source location and emission rate for both wind tunnel experiments.
