In this article computational fluid dynamics analysis of a three-dimensional
compressible and turbulent flow has been carried out through a vortex tube.
The standard k-? turbulence model is utilized in order to simulate an
axisymmetric computational domain. The numerical simulation has focused on
the energy separation and flow field patterns of a somewhat nonconventional
vortex tube, which is on the basis of creating an external hole at the end of
each nozzle. According to the selected nozzles geometry, some of unfavorable
phenomena such as shock wave, high pressure regions and appearing of
unsymmetrical rotating flow patterns in the vortex chamber would be recovered
significantly. In this way the physical parameters of flow field are derived
under different both inlet mass flow rates and outlet pressures of nozzles
hole (OPH). The results show that increasing OPH value enhanced the cooling
capacity of machine in the most of operating conditions.
