摘要

为了探究流固偶合作用对筒装料管道水力运输流场水力特性的影响，采用商用ANSYS Fluent 12.0软件对管道流场和管道双车结构响应进行联合求解，并分析管道双车在平直管道振动运移的水力特性。管道流场计算采用雷诺时均动量方程和RNG k-ε湍流模型，管道双车结构响应计算采用刚体运动方程。结合模型试验，分析轴向流速及测压管水头，并将模拟结果与试验结果对比。结果表明：模拟结果与试验结果一致，最大相对误差不超过5.36%，说明采用流固耦合方法求解管道双车在平直管道振动运移的水力特性是可行的;管道双车瞬时速度与间距均在微小范围内呈不规则振动变化，可将管道双车振动运移视为恒定运动。

Abstract

In order to study effects of fluid-structure interaction on hydraulic characteristics of a pipeline hydraulic transportation flow field for conveying raw material contained in it, a dynamic model for flow field and a piped double-carriage coupled system was established and solved using the commercial software ANSYS Fluent 12.0 to analyze hydraulic characteristics of vibrational transport of a piped double-carriage within horizontal and straight pipelines.The flow field calculation within pipelines was based on Reynolds time-averaged momentum equations and RNG k-ε turbulent model, while dynamic response calculation of the piped double-carriage was done with rigid-body dynamic equations.Combining with model tests, axial velocity distributions and piezo-metric heads were analyzed.Simulated results were compared with test ones.The results showed that simulated results are consistent to test ones, the maximum relative error doesn’t exceed 5.36%, so using the fluid-structure interaction method to solve hydraulic characteristics of vibrational transport of the piped double-carriage within horizontal and straight pipelines is feasible; instantaneous speed and spacing of the piped double-carriage reveal irregular fluctuation within a micro-range, respectively, so vibrational transport of the piped double-carriage can be regarded as a constant motion.
