Vane 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 کاملThe effect of mulch on properties of erosion sensitive soil using a wind tunnel
The aim of this study was to produce mulch by combining natural mineral and organic substances in order to reach soil stabilization and improve soil physical and mechanical properties in Koopal area. The effects of organic mulch (at 3 levels of O1: combination of 1% sugarcane bagasse biochar+0.5% gum Arabic+0.5% gelatin; O2: combination of 3% sugarcane bagasse biochar+1% gum Arabic+1% gelatin; ...
متن کاملVertical axis wind turbine with omni-directional-guide-vane for urban high rise application
A novel shrouded wind-solar hybrid renewable energy and rain water harvester with an omni-directional-guide-vane (ODGV) for urban high-rise application is introduced. The ODGV surrounds the vertical axis wind turbine (VAWT) and enhances the VAWT performance by increasing the on-coming wind speed and guiding it to an optimum flow angle before it interacts with the rotor blades. An ODGV scaled mo...
متن کاملEvaluation 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 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...
