摘要：

This paper describes the effects of energy separation in a vortex tube, which produces cold and hot streams using a Ranque-Hilsch vortex model. A 3D numerical simulation of the convolutions in the flow has been completed. Standard k-epsilon model has been used to solve the governing equations in a compressible flow and turbulent model. The cold orifice diameter and other geometrical characteristics have been studied to see how they affect the performance. ANSYS Fluent is used to simulate a 3D model, with the results showing good agreement with the computational results. While running a conical valve into a vortex tube, the cold orifice to tube diameter ratios of 0.33, 0.416 and 0.5 affect the tube and cold fraction is 0.2 to 0.9. © 2023. Carbon Magics Ltd.
