Abstract:

This paper presents a three-dimensional numerical model of swirled compressible flow in the Ranque-Hilsch vortex tube. We proposed the modification of the energy conservation equation used in Reynolds Averaged Navier Stokes (RANS) numerical simulations. While the additional turbulent heat transfer mechanism caused by gas compressibility is taken into account in the proposed equation, it is not applied in standard RANS models. The data were obtained both by standard and proposed energy conservation equations using the he e turbulence model. The application of the proposed energy conservation equation was shown to increase the accuracy of static and total temperature distribution prediction. The objective of this paper is the demonstration of the applicability of the new numerical model based on the proposed energy conservation equation after the calibration of empirical coefficients.
