Vane Behavior in Vane Compressors Under Start-up Operation

Vane oompressors can not maintain contact between a vane tip and a cylinder wall under start-up operation since backpressure acting on the vane is not sufficient. We theoretically analyzed transient behavior of the vane under the start-up operation by taking account of changes of the backpressure and discharge pressure after compression starting. The validity of the theoretical analysis was con...

Evaluation of Composite Vane Materials for Rotary Sliding Vane Compressors

The physical performance characteristics of composite materials used for vanes in rotary, sliding-vane compressors, in general, are several orders of magnitude more difficult to quantify for design purposes than most homogeneous materials. This arises from the numerous variables that influence the response of these materials under the severe environmental conditions existing in such compressors...

Modeling and Experimental Investigation on the Internal Leakage in a CO2 Rotary Vane Expander

A rotary vane expander has been developed to replace the throttling valve for improving the COP of transcritical CO2 refrigeration system. Due to the serious internal leakage, the expander efficiency is not satisfactory. This paper presents the theoretical and experimental investigation on the internal leakage in a rotary vane expander prototype. Firstly, the leakage flow rate through the inter...
