21. High Temperature Tribology in Hot Stamping
Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : Many automotive components are made of Al-Si coated ultra-high strength boron steel (UHSS) and are produced by hot stamping process. In this process, the workpiece is heated to an austenitizing temperature and is then formed and quenched simultaneously between the tools to achieve the desired shape and high strength. LÄS MER
22. Energy efficiency in a renovated modern office with activity-based work style
Master-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknikSammanfattning : During renovation Ljusåret 2 was converted to a modern office with an activity based work style (ABW) with a Demand Controlled Volume (DCV) ventilation system connected to a closed-loop duct. Cooling is provided through air handling units and active water based beams, the underfloor heating system was kept. LÄS MER
23. Improved interconnect materials for next-generation Solid Oxide Fuel Cells
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Solid Oxide Fuel Cells (SOFC) are attractive candidates in the search for cleaner and energy efficient production due to their numerous advantages such as fuel flexibility, modularity and exceptional efficiencies when combined heat and power is harnessed. A key element in its design are the interconnects which are mainly manufactured from custom ferritic stainless steels to carry the electricity between two adjacent cells. LÄS MER
24. Development of a modern catalytic system for the production of C3+ aliphatic alcohols by the Fischer-Tropsch method
Master-uppsats, KTH/EnergiteknikSammanfattning : This thesis deals with converting a mixture of H2 and CO, also referred to as syngas or producer gas, to higher or mixed alcohols and other fuels through a process called Fischer Tropsch Synthesis (FTS). It is a beneficial pathway that minimizes the dependence on oil and similar fossil fuels which contribute to rapid climate change by releasing harmful greenhouse gases. LÄS MER
25. Improvements to Thermal Management System for Automotive Components
Master-uppsats, KTH/EnergiteknikSammanfattning : Global warming imposes great challenges, and anthropogenic greenhouse gas emissions have to be reduced by active measures. The transportation sector is one of the key sectors where significant reductions are desired. Within a vehicle, the cooling/thermal management system is a subsystem intended for temperature control of automotive components. LÄS MER
