21. Thermoelectric Ba8Ga16Ge30 clathrates for waste heat recovery
Sammanfattning : The modern, highly industrialized, society of today requires huge amounts of energy to function. This has resulted in a heavy dependence on the very energy efficient fossil fuels, a source of energy which of course is not infinite and we are slowly approaching the day when oil runs out. LÄS MER
22. Synthesis and Characterization of New Inorganic Thermoelectric Materials
Sammanfattning : With thermoelectric materials it is possible to convert a difference in temperature into electrical energy. This can be utilized for a more efficient use of available energy, eg. by converting waste heat from a combustion process. LÄS MER
23. Thermal shock and thermal fatigue in ceramic materials
Sammanfattning : This thesis concerns thermal stress fracture in ceramicmaterials. The work describes a new technique for determiningthe thermal shock resistance of brittle materials as well asexperimental results and thermal stress simulations. LÄS MER
24. Robust and Durable Vacuum Insulation Technology for Buildings
Sammanfattning : Today’s buildings are responsible for 40% of the world’s energy use and also a substantial share of the Global Warming Potential (GWP). In Sweden, about 21% of the energy use can be related to the heat losses through the climatic envelope. LÄS MER
25. Engine Thermal Management in Heavy Duty Vehicles
Sammanfattning : Future regulations on noise and exhaust emissions have a large impact on heavy duty engine installations. Cooled EGR is used for NOx abatement. Better sealed engine encapsulations are used to meet new noise regulations. Engine thermal management is therefore becoming an increasingly important discipline. LÄS MER
