11. Numerical Simulations of Cooling Concepts Related to Gas Turbine Combustors
Sammanfattning : The mean by which a gas turbine combustor is cooled is of major importance for the efficiency and emission performance of the machine. The trends of increasing top cycle temperature and leaner combustion have also been accompanied by a need of efficient use of the cooling air. LÄS MER
12. Electron - Ion Recombination Data for Plasma Applications : Results from Electron Beam Ion Trap and Ion Storage Ring
Sammanfattning : This thesis contains results of electron-ion recombination processes in atomic ions relevant for plasma applications. The measurements were performed at the Stockholm Refrigerated Electron Beam Ion Trap (R-EBIT) and at the CRYRING heavy-ion storage ring. LÄS MER
13. Runaway electrons in tokamak plasmas
Sammanfattning : .... LÄS MER
14. Numerical study of flows related to aerated stirred tanks
Sammanfattning : The overall purpose with this work is to investigate the bubbly flow in a aerated stirred tank using numerical simulations. Aerated stirred tanks are commonly used in chemical processes for producing for example insulin and antibiotics. LÄS MER
15. On Radiative Heat Transfer Modeling with Relevance for Combustor and Biomass Furnaces
Sammanfattning : Thermal radiation sometimes is the dominating heat transfer mode in combustion chambers and furnaces and therefore in the design of many relevant industrial facilities prediction of it is necessary. During previous years many research efforts in the radiative heat transfer field have originated and many methods and models from simple to complex have been developed. LÄS MER
