| 摘 要： | 提出了一个换热网络弹性分析的有效方法,该方法以换热网络过程模拟为基础并把灵敏度系数用于过程模拟的调节和加速收敛的过程中.换热网络的模拟过程模仿了一个过程的调节控制过程,在此过程中1],具有干扰变量、控制变量和调节变量,干扰变量可取不同的值,控制变量也可以重新设置.整个弹性分析的过程(包括弹性指数的计算和固定状态的可行性分析)完全象是一个实际过程的操作,回避了以往复杂的数学规划求解问题.本法求解过程具有真实的物理意义,并编制了通用计算机程序并用实例进行了检验.

| Abstract: | A simple and effective approach to calculate flexibility index (CFI) of heat exchanger networks (HEN) is proposed based on process simulation of HEN with help of sensitivity coefficients. The computer programmer is made. If there are manipulated variables in the CFI, when disturbance variables (DVs) change from their normal values and induce the change in the controlled variables (CVs) from their setpoints, the manipulated variables (MVs) will be adjusted in order to make CVs return to their setpoints. The curves of derivations of CVs from their setpoints vs the number of adjustment of MVs can be drawn on the screen. Flexibility test at a fixed state can be done. |
