Autor/autori: Stoian PETRESCU, Monica COSTEA, Charles HARMAN (SUA)

Rezumat: Lucrarea de fata reprezinta inceputul unei prezentari sistematice a dezvoltarii Termodinamicii Ireversibile cu Viteza Finita pentru sisteme complexe. Ea se constituie in trei parti. In prima parte se stabileste expresia Principiului Intai al Termodinamicii pentru procese cu viteza finita in sisteme complexe. Aceasta noua expresie, care reprezinta ecuatia fundamentala a Termodinamicii Ireversibile cu Viteza Finita pentru sisteme complexe, este aplicata, in partea a doua a lucrarii, la studiul procesului ireversibil izoterm cu viteza finita, frecare si laminare. A treia parte contine un studiu al generarii de entropie in procesul izoterm ireversibil.

Cuvinte cheie: procese cu viteza finita, principiului Intai al Termodinamicii pentru procese cu viteza finita in sisteme complexe, Metoda Directa, proces izoterm ireversibil

Abstract: The present paper opens a systematic presentation of the development of Irreversible Finite Speed Thermodynamics in Complex Systems (IFST). It has three parts. In the first part, The First Law for Processes with Finite Speed for Complex Systems is established. This new equation, which is the Fundamental Equation of Irreversible Thermodynamics with Finite Speed in Complex Systems, is then applied for the Isothermal Irreversible Processes with Finite Speed, Friction and Throttling, in the second part. A study on Entropy Generation in the Irreversible Isothermal Process is made in the last part.

Keywords: Finite Speed Processes / First Law for Irreversible Processes in Complex Systems / Direct Method / Isothermal Irreversible Process
