深海管道稳态流动非均匀温度场研究
Non-uniform temperature fields of a deep-sea pipeline in steady flow
摘要
Abstract
To study the non-uniform temperature field of a deep-sea pipeline in steady flow,this paper established a geometric model of a single-layer pipeline and meshed it with GAMBIT.Numerical simulation of the pipeline in steady flow was then conducted under the condition of a non-uniform temperature using FLUENT software.The mesh independence of the system was analyzed,a reasonable method of mesh division was adopted,and the curve of the temperature along the pipeline was obtained.The FLUENT model was verified by comparing the oil temperature results of the numerical simulation with those of the theoretical formula.Finally,parametric analysis of the temperature field of the pipeline was carried out.Study results showed that both the temperature along the pipeline in steady flow and the temperature gradient decreased gradually.The oil inlet temperature,oil inlet velocity,thermal insulation layer thickness,and heat transfer coefficient between the thermal insulator and the seawater influenced the distribution of the pipeline temperature field.This paper provides a reliable reference for the study of non-uniform temperature effects on the pipeline.关键词
