Numerical Study of Frictional Resistance in Vertical Helically Coiled Pipe

摘要

Based on the heat and mass transfer theory and characteristics of the FLUENT software,a numerical simulation platform had been developed to study the heat exchange and flow situation of gas-liquid two-phase flow in vertical helically coiled pipe.The frictional resistance of gas-liquid two-phase flow in the pipe was investigated by this platform.The results show that frictional pressure drop is relatively small under high pressure condition and increases with the increasing gas quality.This platform could provide a good support for the design and research of vertical helically coiled pipe.
