Analog simulation of particle trajectories in a cyclone separator

The trajectories of liquid droplets and dust parti cles in a wet cyclonic scrubber were studied via mathematical modeling on TR-20 analog computers. This simulation study was restricted (1) to two- dimensional flow and (2) by the assumption of Stokes' Law behavior. The penetration of spray droplets into the gas flow field and the time of effective contact with the gas field at high relative velocities were found to be critically dependent on the diameter of the spray droplet and on the angle of injection, in addition to the anticipated dependency on gas flow rate and on projection velocity of the spray particle. It was found that for small particles (<50μ) the drag forces were so high relative to the initial forces that only insignificant penetration of the vapor body occurred, even at a projection velocity of 200 feet per second. At an average rotational air velocity of 50 fps a maximum probability of effective interception and impaction of spray and entrained particles occurred in the region of a spray angle of 30° to the tangent.
