In the present work, a dynamic simulation of the heat transfer process in high pressure laminate (HPL) is carried out, using a mathematical model implemented in Matlab-Simulink is performed. All the system components, the HPL element, the plates, the water storages, etc. are modelled and the dynamical behaviour of the system is studied. Once defined the dimensions of the plate, the heat transfer fluid (subcooled water at 16 bar) and its mass flow rate, detailed parametric studies are conducted. In the heating part of the process, the studies estimate: i) the dimension of the hot tank, ii) the power of the boiler, iii) the thickness of the kraft paper sheets, whilst in the cooling part is possible to determine the dimension of the recovery tank and the temperature which can be reached inside it in a time compatible with the entire process. The calculation of the energy required during heating and recovered during cooling has been evaluated in different configurations. The results show that the modular approach strategy provided by the Matlab/Simulink environment is applicable to the modelling of the entire system, providing faster developing time, and simpler integration with external computational tools.

Abstract
In the present work, a dynamic simulation of the heat transfer process in high pressure laminate (HPL) is carried out, using a mathematical model implemented in Matlab-Simulink is performed. All the system components, the HPL element, the plates, the water storages, etc. are modelled and the dynamical behaviour of the system is studied. Once defined the dimensions of the plate, the heat transfer fluid (subcooled water at 16 bar) and its mass flow rate, detailed parametric studies are conducted. In the heating part of the process, the studies estimate: i) the dimension of the hot tank, ii) the power of the boiler, iii) the thickness of the kraft paper sheets, whilst in the cooling part is possible to determine the dimension of the recovery tank and the temperature which can be reached inside it in a time compatible with the entire process. The calculation of the energy required during heating and recovered during cooling has been evaluated in different configurations. The results show that the modular approach strategy provided by the Matlab/Simulink environment is applicable to the modelling of the entire system, providing faster developing time, and simpler integration with external computational tools.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
