The document summarizes a major assignment presentation on CFD analysis of a vortex tube for refrigeration and air conditioning. It includes an introduction to vortex tubes and their working principle, objectives of analyzing flow parameters and temperature separation, a literature review of previous studies, modeling of a vortex tube with specific dimensions, results and discussion of temperature, pressure, and velocity distributions, applications of vortex tubes, advantages, and conclusions. The presentation aims to optimize design parameters like aspect ratio, number of inlets, and pressures to improve temperature separation performance.
