1. Centrifugal Turbopumps - Flow Physics and Modelling
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : Choices made in the early stages of a design process are crucial. They dictate many of the limitations and freedoms the designer has in later stages of the design. Informed decisions are therefore crucial at this stage. LÄS MER
2. Analytical prediction of turbocharger compressor performance: A comparison of loss models with numerical data
Master-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : One-dimensional models predict the performance of centrifugal compressor in short time, being a helpful design tool in the early design stages. They assume uniform flow through the compressor. Conservation of mass, momentum and energy and some empirical loss correlations are applied to estimate the real outputs. LÄS MER
3. CFD INVESTIGATION OF IMPELLER DIFFUSER INTERACTION EFFECTS ON RADIAL COMPRESSOR STAGE
Master-uppsats, KTH/Kraft- och värmeteknologiSammanfattning : The effects of impeller-diffuser interaction are investigated through numerically simulating the modified wedge vane profiles. Steady and time-accurate, 3D- viscous RANSsolver is used to perform flow field computations. The original design is modified to obtain better aerodynamic performance. LÄS MER
4. A Preliminary Design Tool For Radial Compressors
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : The aim of this thesis has been to implement a computer program capable of modelling radial compressors. The work was conducted at the Division of Thermal Power Engineering, Department of Energy Sciences at the Faculty of Engineering, Lund University. With such a large field as radial compressors, some decomposition of the subject was necessary. LÄS MER
