    Computational evaluation of pollutant dispersion around buildings: estimation of numerical errors

    New search for: Li, Y.
    New search for: Stathopoulos, T.

    This paper presents the numerical simulation of air pollutant dispersion around cubic and rectangular buildings by using the standard k-epsilon turbulence model. Results have been compared with experimental data and past numerical simulation results. The influence of convergence criteria to the numerical solution has been investigated and the discretization error has been estimated by using two different grid systems. Specific threshold values for convergence criteria are recommended.
