Modeling of Air and Dust Flows in the Range of Action of a Round Suction Funnel Above an Impermeable Plane. Part 1. A Mathematical Model and Algorithm for its Computer Implementation.

A mathematical model and computer program for use in calculating the separation region at the inlet to a funnel situated above an impermeable plane are developed by means of stationary discrete vortex rings. The basic computational relationships and algorithms for calculating the characteristic regions of detached flow, the limiting trajectories of dust particles, and the ventilation region are presented.
