Abstract
Heat exchangers are used in a wide range of industrial operations. However, demands like space restriction and weight and greater efficiencies have made compact heat exchangers quite popular. Printed circuit heat exchangers (PCHE) are a promising option due to their compactness and high performance. The present work aims to contribute with the proposition of the physical-mathematical modelling for the evaluation and influence of the geometric factors of the mini channels and their performance. A Computational Fluid Dynamics analysis was performed considering a zigzag mini channels for two different pair of fluids: supercritical CO2-CO2 and air-water. The calculated temperature profiles supercritical CO2-CO2 for compare favorably with available results in literature. The calculated pressure and temperature profiles for air-water indicate that the PCHE studied is suitable for typical applications in offshore oil and gas production.
