AN EXPERIMENTAL INVESTIGATION OF SOME ASPECTS OF THE VORTEX COOLING TUBE,
Abstract
The objectives were to determine the effect of increased vortex tube diameter on the maximum cold temperature obtainable, and to obtain experimental data on internal flow conditions that might be useful in formulating a theoretical explanation of vortex cooling phenomena. The investigation to determine the effect of increasing diameter on performance indicated no significant change in maximum temperature produced when the diameter of the vortex tube was increased from 1.30 to 2.30 inches. It is felt that improved performance that does occur with diameter increases, results from changes in internal flow conditions other than diameter increases. The investigation to obtain sufficient experimental data that would lead to an explanation of the vortex tube cooling mechanism was not successful. It was established, however, that conditions of constant angular flow exist near the surface of the orifice plate. The vortex tube is not a substitute for either expansion cooling or conventional refrigeration. Its one advantage, that of mechanical simplicity, is countered by extreme noise in addition to low efficiency. (Author)
