SINOPSIS

The paper presents an investigation of a vortex tube (VT), operating with closed "hot" valve. A set of experiments conducted showed a substantial decrease of the outlet gas stagnation temperature and rise of the VT wall temperature. For this objective, a VT based heat exchanger was designed and built. The design was named as Vortex Heat Exchanger (VHE). The outlet gas temperature decreased as much as 27°C, depending on the cooling mode. The temperature may fall much lower than the cooling agent temperature. A model of the VHE, developed on the basis of the experimental data, permits prediction of the outlet flow temperature at various regimes.
