  7. Abstract:
  8. Investigation of transport and deposition of aerosol particles has been of interest to researchers in many branches of science. Various numerical and experimental methods has been utilized in particulate fluid flows studies. In recent relevant researches lattice Boltzmann method has been widely used and is reported to be a robust and efficient method. In present study, numerical investigation of dispersion and deposition of aerosol particles is studies in the channel, containing elliptical obstacles geometry using Lattice Boltzmann Method. Fluid flow simulations are performed using LBM while for the study of particle transport and deposition, tracking and the motion equations of them, Lagrangian approach is used.Forces of gravity, drag, saffman and Brownian for the routing of particles is considered.for air flowContaining 10 micron and submicronparticles around an elliptic obstacle in channels problem has been solved.For particles larger than one micron in low Reynolds,gravitationaldeposition is dominant mechanism while in the case of sub-micron particles, Brownian diffusion, is the dominant mechanism.Also in four cases, for different angles of two elliptical obstacles to each other, the flow of air containing particles has been studied.The first case that two obstacles verticallyare placed with the angles relative to each other, in high Reynolds, for all micron and sub-micron particles have highest deposition
