Large-eddy simulation has been used to investigate dispersion under slight and moderate stability conditions. Numerically calculated flow trajectories have been used to follow the paths of a large number of particles released into the turbulent domain in order to study the dispersion properties. The vertical spread from the large-eddy simulations and from a model based on the ideas of Pearson et...
Processes occurring as a result of numerous random molecular events such as molecular diffusion and chemical reactions or equilibriums are well simulated using molecular automata. Neither differential nor statistical equations are required: the macroscopic characteristics of a set of molecules are recreated from the microscopic behaviour of these molecules. Such a method has been applied to elution...
The main subject of the paper is deriving appropriate relationships to calculate the horizontal turbulent diffusion coefficient, the size of the far-field polluted plume and the concentration distribution in the case of the continuous steady state wastewater discharge into receiving marine environment.The simplified advection diffusion-diffusion equation with variable (depending on the distance from...
