Working fluids for high-temperature organic Rankine cycles

Lai, Ngoc Anh; Wendland, Martin; Fischer, Johann - In: Energy 36 (2011) 1, pp. 199-211

Alkanes, aromates and linear siloxanes are considered as working fluids for high-temperature organic Rankine cycles (ORCs). Case studies are performed using the molecular based equations of state BACKONE and PC-SAFT. First, “isolated” ORC processes with maximum temperatures of 250°C and...

Modeling for control of a kinematic wobble-yoke Stirling engine

García-Canseco, Eloísa; Alvarez-Aguirre, Alejandro; … - In: Renewable Energy 75 (2015) C, pp. 808-817

In this paper we derive the dynamical model of a four-cylinder double-acting wobble-yoke Stirling engine. In addition to the classical thermodynamics methods that dominate the literature of Stirling mechanisms, we present a control systems viewpoint to analyze the dynamic properties of the...

Violation of the second law of thermodynamics in the quantum microworld

Čápek, V.; Bok, J. - In: Physica A: Statistical Mechanics and its Applications 290 (2001) 3, pp. 379-401

One of the previously reported linear models of open quantum systems (interacting with a single thermal bath but otherwise not aided from outside) endowed with the faculty of spontaneous self-organization challenging standard thermodynamics is reconstructed here. It is then able to produce, in a...
