Numerical Simulation Of The Energy Separation Effect In The Ranke-Hilsch Tube
Abstract
Currently, there are many applications of vortex technologies. The vortex effect is used in gas-dynamic cold generators and vortex refrigerating chambers. Vortex devices are also used as dehumidifiers, separators, for cooling and heating hydraulic fluids, separation of two-phase media, gas mixtures. Scientists are studying the applicability of vortex equipment for traditional and freeze-drying of agricultural products. However, the influence of the geometric parameters of vortex devices on the performance and energy efficiency of the temperature separation of gas flows has been poorly studied. Research aimed at finding opportunities and expanding the scope of application of vortex tubes is an urgent task. The article describes three-dimensional mathematical models of a swirling gas flow arising in a vortex tube. It presents the results of its implementation in the Comsol Multiphysics 5.6 software package. Thermodynamic and hydrodynamic characteristics confirm the effect of temperature separation in a vortex tube. The dependences of the temperature separation on the flow velocity at are obtained. For the three-dimensional vortex tube model, calculations were carried out using the turbulence model v2-f.
