摘要
通过对试验环道上测试段相关数据的测试,对比分析测试段管壁有沉积物和无沉积物时测试段管壁内温度分布的不同表达式,根据能量方程建立了无量纲温度分布方程,利用贝赛尔函数推导出原油在层流状态下沉积层表面温度分布、沉积层热流密度、油流温度分布等相关温度场的计算公式,为研究蜡沉积规律,定性分析管路结蜡层厚度和制定合理的清管方案奠定了理论基础。
Analysis comps-red with different expression of temperature distribution on deposition and non - deposition in the tested inside - wall of pipeline, a non - dimensional temperature function was founded to get a conclusion according to energy equation. Referring to Besscl function, a calculation equation of temperature distribution in the surface and heat - flow density of wax deposit layer in the lami- nar flow is deduced, as well as temperature distribution inside. This method provides a theoretic basis on the theory law of wax deposit and qualitative analysis on the thickness of wax deposit layer, and it also provides a key theory of making a reasonable clean -up scheme in the transportation pipeline. So it is the practically significant to make a research on the theoretic thickness of calculating wax deposit layer.
