    Abstract

    This thesis is devoted to the dynamics of dispersed small heavy particles (Pp/P>>1)in swirling flows. Stokes drag and gravity are the dominant forces in the equation of motion of heavy particles in a gas flow, in the case of a sufficiently dilute mixture. At sufficiently small Stokes numbers, i.e. the dimensionless particle relaxation time, heavy particles are concentrated in strain regions, whereas they are expelled from regions of high vorticity. An explicit criterion for particle accumulation has been derived in terms of the eigenvalues of the local rate-of-deformation tensor @ui=@xj, in two-dimensional flows as well as in three-dimensional flows.
