Machinerie et outils. Réfrigération Résumé : The effects of the fluid friction acting on the endfaces of the revolving vane (RV) machine, where the cylinder rotates together with the rotor, are investigated analytically with closed form solutions. It was found that the endface losses of the RV machine are generally affected by both the relative velocity and the eccentricity between the rotor and the cylinder. The endface loss of an RV machine with the simply supported bearing arrangement is found to be always lower than that with the cantilever arrangement. When compared to a similar rotary machine but with a stationary cylinder, the RV machine used in this study exhibits a 95% decrease in the endface loss, while in the wider practical dimensions range, an RV machine consistently shows at least a 50% lower in endface loss. These findings supply more proof to the claim of the suitability of the employment of the RV mechanism in high-speed and high-pressure applications.

Design analysis of the novel Revolving Vane expander in a transcritical carbon dioxide refrigeration system / A. Subiantoro in International journal of refrigeration, Vol. 33 N° 4 (Juin 2010) 

Public ISBD [article]  in International journal of refrigeration > Vol. 33 N° 4 (Juin 2010) . - pp. 675-685 Titre : Design analysis of the novel Revolving Vane expander in a transcritical carbon dioxide refrigeration system Titre original : Analyse de la conception d’un détendeur rotatif à palettes dans un système frigorifique au dioxyde de carbone transcritique Type de document : texte imprimé Auteurs : A. Subiantoro, Auteur ; K.T. Ooi, Auteur Année de publication : 2010 Article en page(s) : pp. 675-685 Note générale : Génie Mécanique Langues : Anglais (eng) Mots-clés : Design  Rotary  compressor  Carbon  dioxide  Review  Performance  Expansion Index. décimale : 621.5 Energie pneumatique. Machinerie et outils. Réfrigération Résumé : In this paper, four possible design variants of the Revolving Vane expander have been examined in relation to their application when using CO2 as the working fluid in a refrigeration cycle. The detailed examination of the design components and illustrations are presented and discussed. The study shows that the Revolving Vane expander RV-I design configuration with the vane attached to the rotor and in which the rotor is also used as the driving component is the most superior design. It is found to have the highest mechanical efficiency and the most desirable variation of the power produced.
