Calculation programme for transient thermo-pneumatic flows; Programme de calcul pour les ecoulements transitoires thermopneumatiques

Abstract

With a view to determining the changes occurring in gas reactors after cooling accidents, a calculation programme is established for unidimensional gas flows with pressure drops, heat exchanges and in certain cases blowing, in a reticulated lattice. Any schematization can be taken into account by the use of a set of indices. This programme, of which the FORTRAN list is given, is applied to particular cases of sudden pressure drops in the circuits. The results obtained are in good agreement with those obtained both from the graphical method using the characteristics and from experimental recorded data. (author) [French] En vue de determiner les evolutions des reacteurs a gaz apres accident de refroidissement, on etablit un programme de calcul pour les ecoulements gazeux unidimensionnels avec pertes de charge, echanges thermiques et eventuellement soufflage, en reseau maille. Toute schematisation peut etre prise en compte grace a un jeu d'indices. Ce programme, dont la liste FORTRAN est presentee, est applique a des cas particuliers de degonflage brutal de circuits. Ses resultats sont en bon accord, d'une part avec ceux de la methode graphique des caracteristiques, d'autre part avec des enregistrements experimentaux. (auteur)
