    Numerical Investigation of Nano-Particles Dispersion and Deposition in Curved and Bifurcating Channels using Lattice Boltzmann Method

    , M.Sc. Thesis Sharif University of Technology Tehrani Saleh, Ali (Author) ; Moosavi, Ali (Supervisor)
    Abstract
    Investigation of transport and deposition of aerosol particles attracts interests in many fields of sciences. Various numerical and computational methods has been utilized in particulate 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 performed in curved and bifurcating channels using LBM. Fluid flow simulations are performed using LBM while one-way coupling Lagrangian point of view is used for particle tracking. As the first showcase, transport and deposition of aerosol particles in channel flow with... 

    Simulation of Behavior of a Single Cavitating Bubble Near Solid Boundariesby solvingTwophase Navier-Stokes Equations with a Central Difference Finite Volume Method

    , M.Sc. Thesis Sharif University of Technology Mortezazadeh Dorostkar, Mohammad (Author) ; Hejranfar, Kazem (Supervisor)
    Abstract
    In the present work, the deformation and collapse of a single cavitating bubble near solid boundaries is simulated by solving the preconditioned, homogenous, multiphaseNavier-Stokes equations. Up to now, all studies in the literature performed by the volume of fluid (VOF)approach to capture the bubble surface have been based on the pressure-based category in which the flow variables are calculated through solving the Poisson equation. Here, the density-based category is applied and the solution methodology is based on the artificial compressibility approach. The compressible form of the Navier-Stokes equations is applied inside the bubble and the liquid phase is assumed to be incompressible....
