On parallelization of time-dependent three-dimensional transport equations in air pollution modeling

A parallel time-splitting finite element scheme is developed for three-dimensional first- and second-order closure dispersion models to simulate the plume behavior of a passive contaminant in a convective boundary layer. The simulation results show that the second-order closure model agrees with laboratory data for ground level and elevated sources. The parallel time-splitting finite element method leads to significant speedup of first and second-order closure model calculations.
