Abstract

IN THIS NUMERICAL STUDY, EXERGY ANALYSIS OF A RANQUE-HILSCH VORTEX TUBE HAS BEEN INVESTIGATED. THE THREE-DIMENSIONAL (3D) COMPUTATIONAL FLUID DYNAMIC (CFD) MODEL WHICH IS USED IN THIS STUDY IS A STEADY AXISYMMETRIC MODEL THAT EMPLOYS TWO TURBULENCE MODELS (STANDARD K-E AND STANDARD K-W) TO PERFORM THE COMPUTATION PROCEDURE OF RESULTS. THE CURVES OF ENERGY PERFORMANCE SUCH AS INLET ENERGY, ENERGY OF COLD AND HOT OUTLET, LOST ENERGY AND ENERGY EFFICIENCY HAVE BEEN ACHIEVED FOR THE PRESENT VORTEX TUBE. THESE CURVES HAVE BEEN VALIDATED WITH THE EXPERIMENTAL DATA AND HAVE SHOWN GOOD AGREEMENT. IN THIS PAPER, VARIATION OF ENERGY IN THE COLD AND HOT EXIT HAS BEEN PREDICTED AS A FUNCTION OF COLD MASS FRACTION AND THE BEHAVIORS OF OBTAINED CURVES HAVE BEEN DISCUSSED. IN ADDITION, VARIATION OF TEMPERATURE AND PRESSURE IN THE COLD AND HOT EXHAUST HAS BEEN PRESENTED AS A FUNCTION OF COLD MASS FRACTION. THE RESULTS SHOW THAT THE LOST ENERGY IS MAXIMAL WHEN THE PRESSURE OF OUTLETS REACHES TO MINIMUM VALUE. THE MAXIMUM ENERGY EFFICIENCY OF THIS CASE OCCURS IN A COLD MASS FRACTION OF 0.21 THAT IS APPROVED BY THE EXPERIMENTAL RESULTS.
