In this paper, the author tried to investigate the relation between the profiles of velocity and temperature of the air flowing in a vortex chamber and the dimensions of the main tube, nozzle, cold-end orifice, etc. He obtained data for designing a standard type of vortex tube with high efficiency of energy separation. He also obtained formulae for the profiles of velocity, temperature and energy of the air flowing in a standard vortex chamber, considering the air flow in the annular region as a wall jet. Unlike the formulae represented hitherto, these formulae do not include factors such as radial velocity component or turbulent diffusivity and so may be used to predict the performance or efficiency of a standard vortex tube under any working conditions.
