- Abstract
- The purpose of this study is a numerical simulation of pollutant-laden flow in a boundary layer. The pollutant source is divided Ground-Level Source (GLS) and Elevated source (ES). Air velocity and pollutant particle concentration profile is compared with the experiments in a turbulent boundary layer flow. The code for this research uses Large-Eddy Simulation (LES) model by using Lattice Boltzmann Method (LBM). The Lattice Boltzmann subgrid model predicts more exact solution than previous Reynolds-Averaged Navier-Stokes (RANS) model.
