A study on temperature separation in the vortex tube.
Author(s) : KAEWKAOKIET Y., EIAMSA-ARD S., PIMSARN M., et al.
Summary
This paper reports that increasing the number of inlet nozzles in both insulated and non-insulated vortex tubes affects the temperature distribution and causes temperature reduction in the counter flow vortex tube. From experiments with vortex tubes of 16 mm diameter and cold orifice diameter of 0.5D, we found the maximum temperature reductions at the core for 1,2 and 4 inlet nozzles respectively to be -16, -29 and -30°C. In addition, the cold air temperature drop from employing the snail is higher than those from employing the tangential inlet with 1, 2 and 4 nozzles at the same inlet pressure. For applying the snail to the vortex tube, the maximum cold air temperature reduction and the isentropic efficiency are found to be 33°C and 36%, respectively. Applying dimensional analysis and similarity geometry yielded an empirical correlation for use in designing vortex tubes for optimal performance.
