Vortex tube optimization and modelization

It was discovered by Ranque at 1933, these tubes, which are widely known as "Ranque-Hilsch Vortex Tube, using lots of the places nowadays.In the Fluent coded packet program, the Standard k-¬ epsilon turbulence model is selected.In the study, the effect of plu angle at the hot outlet section, the length to diameter (L/D) ratios and the inlet pressure of a vortex tube, hot and cold exit pressure and temperature values examined. Air and carbon dioxide gases are used.The inlet pressure and temperature selected as 300 kPa pressure and 294 K temperature and the mass flow rate is selected as 0.02 kg/s. The cold mass fractions are selected as 0.3, 0.5, 0.6, 0.7 and 0.8 values are fixed, the result of the iterations the cold and hot exits pressure and temperature values are obtained.
