Carnot performance coefficient and the exergetic efficiency of the combined thermoacoustic machine (thermoacoustic engine – acoustic waves amplifier – refrigerator)

Autor/autori: Dan ANDREI

Rezumat: Determinarea expresiei matematice a randamentului exergetic al maşinii termoacustice combinate de mare putere, care cuplează un generator de unde (motor termoacustic) cu un amplificator de unde şi un refrigerator termoacustic (pulse-tube) dă posibilitatea vizualizării parametrilor asupra cărora putem acţiona pentru mărirea acestui randament.

Cuvinte cheie: randament exergetic, motor termoacustic, amplificator termoacustic, refrigerator termoacustic (pulse-tube), maşina termoacustică combinată de mare putere.

Abstract: The exergetic efficiency of high power thermoacoustic machine, which couples a wave generator (thermoacoustic engine) with wave amplifier and thermoacoustic refrigerator (pulse-tube), shows the way we can increase the efficiency.
