Consideration is given to problems of settling of particles 
of a dispersed impurity from a subsonic jet flow on a curvilinear 
surface. Flow of the carrier medium is modeled based on the equations 
of vortex flow of a nonviscous incompressible liquid; they are written 
in the stream function-velocity vortex variables. The interaction 
of plane and round jets with obstacles of different shapes for the 
zero and nonzero initial vorticities of the flow is modeled numerically. 
The coefficient of sedimentation of the impurity is calculated as 
a function of the particle size and the obstacle shape.
