Changes in solvent-solute induced polarities caused by variations in solvent density affect excess enthalpies of a solution. When the solution serves as the working fluid for a transcritical power cycle, changes in solvent-solute bonding energies between the solvent in its dense liquid and less dense supercritical fluid state can favorably impact the cycle’s energy conversion potential. Energy transfers internal to the cycle caused by changes in induced polarities challenge Carnot’s and Clausius’s original assumptions that heat energy is the lowest form of energy to which all other forms degrade.
Les changements dans les polarités induites du solvant-soluté provoqués par les variations de la densité du solvant affectent les enthalpies excessives de la solution. Lorsque la solution sert de fluide de travail pour un cycle de puissance transcritique, des changements dans les énergies de liaison solvant-soluté entre le solvant dans son liquide dense et dans un état de fluide supercritique moins dense peuvent influencer favorablement le potentiel de conversion énergétique du cycle. Les transferts d’énergie interne au cycle causés par des changements dans les polarités induites contestent les postulats initiaux de Carnot et Clausius qui affirment que l’énergie calorifique est la plus basse forme d’énergie à laquelle toutes les autres formes se dégradent.
