摘要
为求得油轮货油舱温度场,在简化原油的热物性参数和边界条件的基础上建立了一个二维模拟“阻-容”网络。根据该网络,用“节点电位法”写出一组温度的差分方程,用微型计算机计算,其结果以表格和曲线的形式给出。计算的温度场变化情况与实测的基本相符。这对在运输过程中控制原油加热温度具有一定的参考价值。
In order to find the numerical value of the oil temperature field in an oil tank,some idealized parameters and boundary conditions are discussed, and on their basis a twodimensional simulative 'resistor-capacitor'network is set up. According to the nework a set of temperature difference equations is written by the use of 'Node Voltage Method'. Calculation is carried out on a microcomputer and the results are given in tables and curves. The responses calculated are very close to those actually measured. The method proposed is useful for controlling the cargo oil heating temperature during shipping.
