A great number of heat transfer problems can be treated as transient heat transport phenomena within a body, often semi-infinite or symmetric in some directions, and in these cases a one-dimensional treatise is enough. Dielectric/microwave heating of cylinder and fast cooling of thin slabs are common examples. A numerical code was developed to simulate heat transfer phenomena in variable conditions. Model equations were based on transient one-dimensional energy balance. Moreover, the different kinds of energy source terms, and the different kinds of boundary conditions can be implemented in the model. Aim of this communication is a preliminary validation of the numerical code, by comparison with several analytical solutions of the heat transfer problems coming from literature. The validation has been carried out, and here results are shown and briefly discussed. 10.1007/s00231-002-0341-8

Abstract
A great number of heat transfer problems can be treated as transient heat transport phenomena within a body, often semi-infinite or symmetric in some directions, and in these cases a one-dimensional treatise is enough. Dielectric/microwave heating of cylinder and fast cooling of thin slabs are common examples. A numerical code was developed to simulate heat transfer phenomena in variable conditions. Model equations were based on transient one-dimensional energy balance. Moreover, the different kinds of energy source terms, and the different kinds of boundary conditions can be implemented in the model. Aim of this communication is a preliminary validation of the numerical code, by comparison with several analytical solutions of the heat transfer problems coming from literature. The validation has been carried out, and here results are shown and briefly discussed. 10.1007/s00231-002-0341-8I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
