Modeling of Air and Dust Flows in the Range of Action of a Round Suction Funnel Above an Impermeable Plane. Part 2. Characteristics of Separation Region and Efficiency of Capture of Dust Particles1

Current near a round local ventilation suction port in the form of a funnel situated above an impermeable plane is considered. Limiting trajectories of dust particles are constructed in the velocity field found from a new computer program and the capture coefficient as a function of the slope and le...

Zusammenfassung:	Current near a round local ventilation suction port in the form of a funnel situated above an impermeable plane is considered. Limiting trajectories of dust particles are constructed in the velocity field found from a new computer program and the capture coefficient as a function of the slope and length of the funnel and distance from the plane is determined. The geometric dimensions of the separation region at the inlet to the funnel as functions of the distance from the plane and the length of the funnel are determined.
