一种关于焦炭塔展开后的二维平面温度场的重构方法

在求解焦炭塔的整体温度场的问题时,对焦炭塔模型进行了结构简化,将焦炭塔展开为二维平面矩形,并通过重构二维矩形面的温度场来得到焦炭塔的整体温度场。文章通过采用的11个温度传感器在焦炭塔上进行布置,并对简化的焦炭塔进行展开,通过找到相邻节点间的温度关系式建立方程组,进而求解出矩形面内的所有的节点温度。所求节点温度即为划分网格后的各个小矩形面的顶点温度。最后,采用形函数内插的方式,得到各个小矩形面内的温度并进行拼接可以得到最终所需要的焦炭塔的二维平面矩形温度场。

In order to solve the problem of the whole temperature field of the coke drum,the structure of the coke drum model is simplified,the coke drum is expanded into a two-dimensional plane rectangle,and the whole temperature field of the coke drum is obtained by reconstructing the temperature field of the two-dimensional rectangle.In this paper,11 temperature sensors are arranged on the coke drum,and the simplified coke drum is expanded.By finding the temperature relationship between adjacent nodes,a set of equations is established,and then all the node temperatures in the rectangular plane are solved.The calculated node temperature is the vertex temperature of each small rectangular surface after mesh generation.Finally,the temperature in each small rectangle can be obtained by shape function interpolation,and the final two-dimensional temperature field of coke drum can be obtained by splicing.
