Analysis of the effect of multiphase fluids during the boiling process of refrigerants diluted or undiluted with miscible oils

This project focuses on the comprehensive analysis of the boiling behavior of pure refrigerants and those mixed with fully miscible lubricating oils. The primary motivation is the search for alternatives to refrigerants with high Global Warming Potential (GWP) and Ozone Depletion Potential (ODP), aligning with global sustainability efforts. The refrigerant-lubricant oil mixture is investigated with the fundamental purpose of modifying thermophysical properties and, crucially, improving heat transfer coefficients to achieve energy and economic savings. The methodology combines qualitative and quantitative studies. The first phase includes theoretical design and the construction of experimental equipment to determine thermal transport properties, which must operate for a minimum of six months. The second phase focuses on the experimental analysis of flow patterns and defects in refrigerant circulation within the piping. Finally, a numerical simulation of the flow through the piping network will be conducted to contrast the numerical results with the experimental data obtained.<br/><br/><b>Goal</b>: <br/>To analyze the effect of multiphase fluids, specifically refrigerants diluted or undiluted with miscible oils, during the boiling process. A secondary objective is to investigate how this mixture affects heat transfer coefficients and thermophysical transport properties.<br/><br/><b>Research lines</b>: <br/>Modeling and simulation applied to industry
