1) rough tube
粗糙管道
2) piping coarseness
管道粗糙度
3) rough channel
粗糙通道
4) rib-roughened tube
肋粗糙管
1.
Turbulent heat transfer in smooth tube and rib-roughened tube were numerically simulated.
肋粗糙管是包装设备的一种重要管道,采用数值模拟方法对光滑圆管与肋粗糙管内的湍流传热进行计算,根据数值模拟的结果计算了传热滞流底层与湍流主区内的热阻,计算结果显示贴近壁面的薄滞流底层的热阻约占总热阻的一半,是影响传热的主要区域;肋粗糙管通过表面粗糙减小了热阻,促进了传热。
5) rough surface tube
粗糙管
1.
Based on functions R and G reflecting the flow and heat transfer characteristics of rough surface tubes, coupled with the second law of thermodynamics (entropy generation analysis) and qualitative consideration of rough surface tubes production cost, the comprehensive analysis and evaluation of enhanced heat transfer performance on rough surface tubes are made.
以反映粗糙管流动和传热性能的Ｒ函数和Ｇ函数为基础，结合熵产分析法，并在定性考虑粗糙管制造成本等因素的条件下，对粗糙管的强化传热性能进行了综合分析和评价。
6) rail roughness
轨道粗糙度
1.
Based on random rail roughness and vehicle-bridge coupling element, a method is proposed for calculating random vibration of long span bridges under moving vehicles in this paper.
基于随机轨道粗糙度和车桥偶合单元,提出了大跨桥梁移动车辆荷载作用下随机振动的计算模式。
