1. On Film Cooling of Turbine Guide Vanes : From Experiments and CFD-Simulations to Correlation Development
Sammanfattning : To achieve high thermal efficiency in modern gas turbines, the turbine-inlet temperature has to be increased. In response to such requisites and to prevent thermal failure of the components exposed to hot gas streams, the use of different cooling techniques, including film cooling, is essential. LÄS MER
2. Thermoplastic processing of starch and cellulose-containing polymers
Sammanfattning : Starch and cellulose are two naturally occurring polymers that have the potential to reduce the dependence on fossil resources if used as replacements or as complements to synthetic polymers. There are however some problems associated with the use of these polymers that have to be addressed and solved. LÄS MER
3. Unstable flow of molten polymers
Sammanfattning : .... LÄS MER
4. Investigations of Heat Transfer and Fluid Flow in the Pocket Region of a Gas Turbine Engine and Cooling of a Turbine Blade
Sammanfattning : In the present work, heat transfer within gas turbine applications are investigated bothexperimentally and numerically. The main content concerns heat transfer and fluidflow over the pocket region and cooling of a turbine blade. LÄS MER
5. Influence of processing and processing additives on the degradation of aliphatic polyesters
Sammanfattning : Poly(3-hydroxybutyrate-co-3-hydroxyvalerate), P(3HB-co-3HV),poly(ε-caprolactone), PCL, and poly(lactic acid), PLA,have been subjected to film-blowing, melt-extrusion andmelt-pressing. The influence of processing conditions andprocessing additives (i.e. plasticizer, antiblocking and slipagents) on properties and degradation have been studied. LÄS MER
