11. MODELLING OF HEAT TRANSFER OF RAILWAY SWITCH HEATING
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Switches and crossings are vital components of the railway network. Obstacles to the smooth functioning of these components could result in delays and network traffic. Given the geographical location of Sweden, snow is one of the major obstacles for the switches.

12. An analytical method for quickly evaluating the performances of refractory alloys in sCO2 Brayton cycle applications
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : A rapid and effective analytical method has been developed to assess the performance of structural materials in sCO2 power cycle applications. This method combines a conjugate heat transfer model, considering constant heat flux boundary conditions, with a corresponding mechanical model. LÄS MER
13. Theoretical examination of temperature distribution in an electrical furnace by the study of transient heat conduction effects
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/MaterialteoriSammanfattning : The company Kanthal produces electric heating elements that require high temperature treatment in one production step. In this process step, called sintering, the amount of heat received by the sintered material is in direct correlation to the product’s outcome. LÄS MER
14. Thermal Analysis of Tap- Changers
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad mekanikSammanfattning : This thesis provides a way of mapping the temperature development of the tap-changer oil for some different standardized loading cases. The project was in collaboration with Hitachi Energy for one of their production cites situated in Ludvika, Sweden. The software used for the simulation environment was COMSOL 6.1 which is a finite element solver. LÄS MER
15. Numerical Modelling of a Packed Bed Thermal Energy Storage for Applications in a Carnot Battery : KTH Thesis Report
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : This thesis explores the heat transfer characteristics of a packed bed thermal energy storage device through the development of a 3D model in COMSOL Multiphysics. The model is based on a laboratory-scale device consisting of an aluminum box filled with sand, which acts as the thermal storage medium. LÄS MER
