The dynamics of the separation of gas mixtures in the field of a sound wave
Abstract
The dynamic aspects of the spatial separation of binary molecular gas mixtures and helium in the field of a sound wave has been investigated experimentally. The concentration of the heavy components in the gas mixtures was in the range 0.01-0.1. Sound pressure in the cavity was up to 90,000 dyne/sq cm (bar) and mixture pressure was 760 torr. An increase in the degree of separation of acoustic vortex flows due to a radial temperature gradient and circulation enhancement was observed. A general mechanism for the separation is discussed. Experimental measurements of the extent of flow separation are compared with predicted values in a table.
