Mikhaylenko C.I. Vortex tube modelling: outlet parameter dependencies of cold air production // J. Phys.: Conf. Ser. 2019. V. 1158. 032032

Аннотация:

A model of a counterflow vortex tube has been prepared to study the dependence of the influence of the parameters of cold and hot outlets on the production of cold air. For a fixed geometry of the vortex tube, a simulation is performed with an independent change of the length of the cold outlet nozzle, the angle of the widening of the cold outlet nozzle, and the hot outlet area. In a series of experiments, the pressure of air supplied to the inlet varies in order to take into account the possible effects of computational and model errors. An anomalous increase in the temperature of the outgoing air was observed with a hot outlet area of ~30 cm2. Conclusions were drawn about the range of reasonable values of the outlet parameters for the considered configuration of the vortex tube.
