| Abstract: | This paper sets up a simulator of heat exchanger networks that con-sists of heat exchangers,mixers and splitters.Calculating order of subsys-tems which can be solved separately is determined by the decomposition ofthe system.For loop-subsystem,the minimum number of broken streams issolved,and meanwhile calculating order of their units is determined.Basicproperty data-base of some substances and structural parameter data-base ofheat exchangers are built.A correction heat-transfer-unit method of solvingtemperature of streams through the heat exchangers is proposed,and theoutcome is a detailed output.Many examples are simulated and the resultsare satisfactory. |
