Abstract

In order to solve the liquefacient problem of the natural gas, this essay adopts high-pressure vortex tube with air as a medium, and studies the effect of the inlet to the performance of high-pressure vortex tube. The numerical simulation results demonstrate that with the increase of the ratio of the cooling air, the temperature of high-pressure vortex tube refrigeration effect will decrease at first, then increase gradually, and decrease again finally. However, the Heating part, the cooling capacity of the unit and the coefficient of performance will grow bigger with the ratio of the cooling air increasing.
