Method of Measurement Viscosity of Oil Using Inclined-tube and Bowl;
利用斜管滚球测量原油黏度的方法
The new de-oiling settler of two-stage inclined pipe settling wall was divided into two stages.
新型的双级斜管沉淀墙除油沉淀器分为两级,前一级为异向流斜管沉淀和粗粒化除油,后一级为斜管隔油。
The regenerated catalyst line and other special areas of a 26,000 b/d heavy oil FCC unit in SINOPEC Jinling Company experienced lining spalling of large area and hot wall problems.
30Mt/a重油催化裂化装置再生斜管过渡段等特殊部位多次出现红斑等衬里问题,分析其原因如下:(1)施工不均匀;(2)施工工期过短,使斜管衬里预制部分和现场施工部分没有较好的过渡;(3)再生斜管运行条件恶劣;(4)特殊部位衬里的材质无法满足生产需要。
Characteristics of oil-gas-water three-phase flow pattern in horizontal and slightly inclined pipes;
水平及微倾斜管内油气水三相流流型特性
Since gravitation and inclination angles, the flow patterns in inclined pipes are different from those in vertical pipes.
叙述了近年来国内外对油水两相流流型及流型转化的研究状况,介绍了在垂直管、倾斜管及水平管中的流型和倾角对流型存在范围的影响,对于不同倾角管中油水两相流流型进行了对比。
Numerical analyses are conducted for combined free and forced laminar convection in the thermal entrance region of inclined pipes with buoyancy-aided flow.
用数值分析方法研究了倾斜管内热进口段自然强制同向复合对流传热 ,分析了浮力、倾斜角及轴向导热对流动和传热特性的影响 ,得到了速度、温度、壁面剪切应力、局部及平均Nusselt数的分布和变化 研究结果显示Pe=71时平均Nusselt数的最大值位于 2 5°～ 45°之间 ,Pe=2 5时则在 90°处出现 。
