Numerical Investigations of Compressible Flow and Energy Separation in a Counter-Flow Vortex
ABSTRACT
This paper presents a numerical modelling of the strongly swirling turbulent compressible flow and temperature/energy separation in a counter-flow vortex tube. A comprehensive two-dimensional vortex tube model is developed which incorporates an algebraic Reynolds stress model (ASM). Computations, based on a finite volume method, were carried out by utilising the k-ε model and the ASM for the closure of the second-order correlation moments in the governing equations. The modelling of turbulence for compressible, complex flows used in the simulation is discussed. The numerical results for a counter-flow vortex tube describe the detailed characteristics of the axial/tangential velocity, static/total pressure, static/total temperature fields based on the k-ε model and the ASM, which are the important to design and operation of the vortex tube.
