Phase Heat Transfer And Pressure Drop Inside Internally Helical-Grooved Horizontal Small-Diameter Tubes

Abstract

In this thesis analytical investigations are done to determine heat transfer and flow characteristics of water flowing through horizontal internally helical grooved tubes. Different materials used for tubes are steel and copper. The investigations are made by changing the pitch value 3mm & 3.5mm for helical grooves. The CFD and Thermal analysis are carried out for different refrigerants R32 and R410A for turbulent and laminar flows. CFD analysis is done to determine heat transfer coefficient, pressure drop, heat transfer rate and Thermal analysis is done to determine temperature distribution and heat transfer rate. Modelling is done in Creo 2.0 and analysis is done in Ansys.
