Study of a vapor-compression air-conditioning system for jetliners
(Lappeenranta University of Technology, 2009-11-04)
Most modern passenger aeroplanes use air cycle cooling. A high-speed air cycle is a reliable and light option, but not very efficient. This thesis presents research work done to design a novel vapour cooling cycle for ...
Performance Improvement of Centrifugal Compressor Stage with Pinched Geometry or Vaned Diffuser
(Lappeenranta University of Technology, 2009-10-01)
Centrifugal compressors are widely used for example in refrigeration processes, the oil and gas industry, superchargers, and waste water treatment. In this work, five different vaneless diffusers and six different vaned ...
Computational Analysis and Optimization of Real Gas Flow In Small Centrifugal Compressors
Small centrifugal compressors are more and more widely used in many industrialsystems because of their higher efficiency and better off-design performance comparing to piston and scroll compressors as while as higher work ...
Experimental and Numerical Analysis of Different Volutes in a Centrifugal Compressor
In a centrifugal compressor the flow around the diffuser is collected and led to the pipe system by a spiral-shaped volute. In this study a single-stage centrifugal compressor with three different volutes is investigated. ...
