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...
متن کاملVane Dynamics Analysis of a Tilted Vane Rotary Compressor
An analytical model of vane dynamics in a tilted vane rotary compressor is presented. With the geometric relationship of the vane in a tilted slot, and the roller, the kinetic equations were derived for evaluating the reciprocating inertial force of the vane, and the chamber volume equations were obtained for calculating pressure history inside the compression chamber. The empirical friction co...
متن کاملVane 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...
متن کاملSymmetrizing Evolutions
The importance of the notion of symmetry in quantum theory cannot be overstimated [1]. The associated statespace decomposition into dynamically invariant sectors is a highly desirable property in that it can strongly simplify the analysis of the system evolution. Suppose that on the state-space H of a quantum system S acts a group G via a representation ρ. In general the Hamiltonian H of S is n...
متن کاملRandom Evolutions
This article gives a short presentation of random evolutions. At first, the following two examples are presented: dynamical stochastic systems and increment processes both in Markov media. After, an introduction to semi-Markov Random evolution in a Banach space is given, where the previous evolutionary systems are obtained as particular cases. Finally, two abstract limit theorems of average and...
