摘要
基于FLUENT建立传感器温度测量以及管道内液氮流动的数值计算模型,计算并分析对于与管壁不同接触面积、管道上不同安装位置、液氮不同流速以及不同管长条件下温度传感器所测温度变化规律以及影响温度传感器测量出的温度值与管内流体温度之间差异的因素。
Based on Fluent, numerical calculation model of liquid nitrogen flow and platinum resistance thermometer were established to calculate and analyze the measurement results of thermometer under the conditions of different contact area with tube wall, different installation location, different velocity of liquid nitrogen and different pipe length. At the same time, the factors which influence the difference between measured pipe wall surface temperature and internal fluid temperature is analyzed.
