Abstract

In a particularly reliable and flexible process for simulating the behaviour of a technical installation in which a medium existing in a plurality of phases (W, D) circulates in a partial region, according to the invention a heat flow (Qfg) and a mass flow (Mfg) between two phases (W, D) are detected by means of a linear combination of differences from derivations of the entropy (Sf, Sg) of the phase concerned (W, D) according to the internal energy (U) or the mass (mm, mg) of the phase concerned. The linear coefficients (Lij) of an equation system derived from the linear combinations form a symmetrical matrix. As an application of irreversible thermodynamics to the simulation process there arise on the one hand representations for the mass and heat flows (Mfg, Qfg) as a function of "forces" and on the other relations between the flows (Mfg, Qfg) based on the Onsager relation.
