Abstract
A plane, laminar two-phase jet flow is considered, where the two-phase medium in the jet consists of small spherical solid particles suspended in an incompressible carrier fluid The development of the jet flow is studied in the presence of a moving free stream, containing no particles and alined with the jet. Diffusion of particles as well as the effect of carrier- and particle-phase viscosity is taken into account. A perturbation analysis is performed based on small particle concentration and small velocity differences between jet- and free-stream speed. Accordingly, the derived linear equations are solved byLaplace transforms. Resutiing expressions for particle velocity profiles contain two parameters. One of these is the ratio of the carrierReynolds number and the particle velocity relaxation parameter, and the other is the ratio of the particle diffusion coefficient and the carrier fluid viscosity. It is shown that both parameters can have a profound influence on the solution.
