THE DISSIPATION TEMPERATURE: A TOOL FOR THE ANALYSIS OF MALFUNCTIONS IN THERMOMECHANICAL SYSTEMS

摘要

The aim of this paper is to define and characterize a new parameter, the dissipation temperature. When a thermal plant component displays an internal deterioration (intrinsic malfunction), its performance gets worse. This fact is reflected in a variation of the internal parameters that describe its behavior (isentropic efficiency, effectiveness, pressure and/or temperature ratios, parameter θ [1]). On the other hand, the remaining components of the plant may be affected (by induced malfunctions) because they are working under different operating conditions with respect to the rated ones.
