摘要

为了分析管道车振动运移时管道流场水力特性,采用Fluent软件对管道车结构响应与管道流场特性联立求解,其中管道流场计算采用雷诺时均动量方程,管道车结构响应计算运用结构动力学方程。结果表明:利用流固耦合数值模拟分析管道车在平直管道振动运移水力特性是可行的。管道车在平直管道平动速度在微小范围呈不规则波动,可将管道车运动视为振动运移。随着管道车直径比增加,管道平均压降系数呈先减小后增大,而管道车机械效率却呈先增大后减小。该研究将对掌握管道车振动运移时流速与压强的变化规律具有重要参考价值。

Abstract

Here, to analyze hydraulic characteristics of pipeline flow field when pipeline vehicle vibrates and moves, the software Fluent was used to simultaneously solve structural response of the pipeline vehicle and characteristics of the pipeline flow field.Reynolds time average momentum equations were used to calculate the pipeline flow field, and structural dynamic equations were used to calculate structural response of the pipeline vehicle.The results showed that it is feasible to analyze hydraulic characteristics of vibration migration of pipeline vehicle in straight pipeline by using fluid-structure interaction numerical simulation analysis; the translational velocity of the pipeline vehicle fluctuates irregularly within a very small range in straight pipeline, so the motion of the pipeline vehicle can be regarded as vibration migration; with increase in diameter ratio of the pipeline vehicle, the pipeline average pressure drop coefficient firstly decreases and then increases, while the mechanical efficiency of the pipeline vehicle firstly increases and then decreases; the study can have important reference value for mastering variation laws of flow velocity and pressure during vibration migration of pipeline vehicle.
