Dynamic modelling and simulation of plate heat exchangers

关于换热器动态建模仿真的研究文章 摘要如下： This work presents the mathematical modelling and simulation of complex plate heat exchanger arrangements under milk fouling, using detailed dynamic models. A complex fouling model based on a reaction/mass transfer scheme is coupled with a general thermal dynamic model of plate heat exchangers. All the important factors a!ecting milk heat treatment are formally quanti"ed. The "nal model comprises a set of partial di!erential, integral and algebraic equations. Parameter estimation analysis is performed based on the solution of a dynamic optimization problem. The simulation results are in a good agreement with available experimental work. Three di!erent con"gurations with complex #ow arrangements are considered to illustrate aspects of fouling behaviour. The simulation results provide signi"cant insight into the key factors a!ecting milk fouling. ( 2000 Elsevier Science Ltd. All rights reserved.
