Artificial lift technique of multistage sliding vane pump used in thermal production well

Matching Diffuser Vane with Return Vane Installed in Multistage Centrifugal Pump

The effects of the diffuser vane on the performances of the multistage centrifugal pump were investigated experimentally, taking account of the interactions among the diffuser vane, the return vane, and the next stage impeller. It is very important to match well the diffuser vane with the return vane, for improving the hydraulic efficiency of the pump. The efficiency may be more improved by mak...

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...

Thermal processing of strained InGaAs/GaAs quantum well heterostructures bonded to Si via an epitaxial lift-off technique

We have investigated the effects of thermal cycling on the optical properties of In0.2Ga0.8As/GaAs single quantum well films bonded to Si~001! via the epitaxial lift-off technique. The optical and structural quality of the bonded films were monitored using cathodoluminescence ~CL! imaging and spectroscopy. The films were stable through the temperature range ~500–700 °C! used in normal InxGa12xA...
