EXPERIMENTAL STUDY AND CFD ANALYSIS ENERGY SEPARATION IN A COUNTER FLOW VORTEX TUBE

Abstract

In this manuscript, both experimental and numerical investigations have been carried out to study the mechanism of separation energy and flow phenomena in the counter flow vortex tube. This manuscript presents a complete comparison between the experimental investigation and CFD analysis. The experimental model was manufactured with (total length of 104 mm and the inner diameter of 8 mm, and made of cast iron) tested under different inlet pressures (4, 5, and 6 bar). The thermal performance has been studied for hot and cold outlet temperature as a function of mass fraction, a, (0.3-0.8). The 3-D numerical modeling using the k-e model used with code (FLUENT 6.3.26). Two types of velocity components are studied (axial and swirl). The results show any increase in both cold mass fraction and inlet pressure caused to increase ΔT
