For presentation at the American Rocket Society Annual Meeting, November 16-21, 1959. The results of a study of the hydrodynamics of a twocomponent gaseous-vortex system are presented. Analytical expressions for tangential velocity and staticpressure profiles in a turbulent vortex showed gocd agreement with experimental data. Air-flow rates from 0.075 to 0.14 lb/sec and corresponding tangential velocities from 160 to 440 fps were correlated by turbulent Reynolds numbers from 1.95 to 2.4. An analysis of an air-bromine gas mixture in a turbulent vortex indicated that a boundary value of bromine-to-air radial velocity ratio (u/sub 2//u/sub 1/)/sub 0/ of 0.999 gave essentially no bromine buildup, whereas a value of 0.833 resulted in considerable separation. For a constant value of (u/sub 2//u/sub 1/)/sub 0/, the bromine buildup increased as (1) the tangential velocity increased, (2) the air-to-bromine weight-flow ratio decreased, (3) the air-flow rate decreased, (4) the temperature decreased, and (5) the turbulence decreased. Analytical temperature, pressure, and tangential-velocity profiles are presented. Preliminary experimental results indicated that the flow of an air-bromine-mixture through a vortex field results in a bromine density increase to a maximum value, followed by a decrease; the air density exhibited a uniform decrease from the outer vontex radius to the exhaustnozzle radius.
