1. Coordinated Control of HVDC Links in Transmission Systems
Sammanfattning : Dynamic security limits the power transfer capacity between regions and therefore has an economic impact. The power modulation control of high-voltage direct current (HVDC) links can improve the dynamic security of the power system. LÄS MER
2. Fluid Flow Phenomena, Inclusion Characteristics and some Heat Transfer Phenomena during Filling of an Ingot Mmold
Sammanfattning : Clean steel production requires a good understanding of theinclusion characteristics at all stages of the steelmakingprocess. So far there exist little information about theformation and evolution of inclusions during the filling ofingot molds. LÄS MER
3. Heat transfer,inclusion characteristics and fluid flow phenomena during up-hill teeming
Sammanfattning : Clean steel production requires good control of the sizedistribution and the composition of the inclusions at allstages of the steel making process. So far, there exists verylittle information on the behavior of the inclusion populationduring ingot casting of steel. LÄS MER
4. High-temperature degradation of plasma sprayed thermal barrier coating systems
Sammanfattning : Thermal barrier coating systems (TBCs) are used in gas turbines to prevent high-temperature degradation of metallic materials in the combustor and turbine. One of the main concerns regarding TBCs is poor reliability, and accurate life prediction models are necessary in order to fully utilise the beneficial effects of TBCs. LÄS MER
