Abstract
Aerosols are produced in a large number of industrial precesses over a wide range of sizes. Of particular importance is deposition of coal and oil combustion aerosols in turbines. A model coupling the transport and the dynamics of aerosols to flow characteristics in gas turbines is presented. An order of magnitude analysis is carried out based on typical operational conditions for coal and oil combustion (neglecting coagulation) to determine the relative importance of various mechanisms on particle behavior. A scheme is then developed to incorporate a moment model of a lognormally distributed aerosol to predict aerosol transport and dynamics in turbine flows. The proposed moment model reflects the contributions from convection, inertia, diffusion and thermophoresis. Aerosol behavior in various laminar 2-D and axisymmetric flows is considered in this study. Results are compared to published work in 1-D and 2-D planar and axisymmetric.
