Abstract

The coupling of flow and aerosol behavior is important in a variety of fields ranging from the design of industrial manufacturing processes to prediction and control of pollutants. This paper suggests a method for coupling flow and aerosol transport and dynamics into a single 2-D\Axisymmetric\3-D code which can predict the behavior and evolution of aerosols in arbitrary geometries. Viscous compressible flow is described by the Reduced Navier-Stokes (RNS) equations and the polydisperse particle behavior by an Eulerian aerosol moment model which accounts for particle transport due to convection, diffusion (Brownian and turbulent), inertia and thermophoresis, as well as particle\particle and gas\particle dynamics due to coagulation, nucleation and condensation. Flow and aerosol behavior are computed in separate modules and coupled through an iterative procedure. The influence from any component, e.g. flow or aerosols can thus be easily decoupled, as can subcomponents, e.g. viscosity, compressibility, or aerosol transport or dynamics. Using this method it is possible to directly determine detailed aerosol behavior for a wide range of applications. Present studies are focused on behavior of flow and particles in two and three dimensional compressible and incompressible internal and external geometries. Flow and aerosol behavior in nozzles, inlets and ducts are presented.
