MODELING AND SIMULATION OF COMPLEX MECHANICAL SYSTEMS WITH APPLICATIONS TO A STEAM-GENERATING SYSTEM .1. MATHEMATICAL-MODELING

The authors' objective is to simulate a steam-generating system when t he real parameters of the process can be measured only at a few locati ons. In this context it is necessary to define a functional structure and to model the longitudinal distribution of the physical phenomena. To reconstruct the real parameter distributions, it is necessary to ta ke into account the heat and mass balance equations. These equations a re elaborated with the help of a control volume. The resulting models of the transportation and transformation elements are used as a first step to define the system concept. Part 2 will be devoted to the numer ical simulation.
