Some types of difficulty encountered during the simulation of heat exchangers (1961); Quelques types de difficultes rencontrees lors de la simulation des echangeurs (1961)

Abstract

After recalling that the simulation of exchangers poses problems which are often difficult to solve, the author points out that these problems appear first of all when the physical phenomena are described in terms of equations. They appear also during the solving of the equations since expressions which are more and more complex can give rise to unstable electronic structures. These difficulties are developed during the analysis of various types of exchangers and in each case the solutions chosen are given. (author) [French] On rappelle que la simulation des echangeurs pose un certain nombre de problemes souvent difficiles a resoudre. Les difficultes apparaissent d'abord lors de la mise en equations des phenomenes physiques; elles apparaissent ensuite au moment de la resolution, car des formulations de plus en plus complexes peuvent donner lieu a des structures electroniques instables. On developpe ces difficultes en faisant l'analyse de quelques types varies d'echangeurs et l'on indique dans chacun des cas les solutions qui ont ete retenues. (auteur)
