21. Experimental Investigation of the Aerodynamics and Heat Transfer in an Intermediate Turbine Duct
Sammanfattning : In today’s aero engines with large bypass ratios, the difference in diameter between the high pressure turbine and the downstream turbine, being either an intermediate or low pressure turbine, is large. There is also scope to further increase it, in order to increase the efficiency of the downstream turbine and enabling use of larger diameter fans. LÄS MER
22. Experimental and Numerical Investigations of Heat Transfer related to Gas Turbine Applications
Sammanfattning : Gas turbines are broadly used in aerospace and marine propulsion and power production etc.Investigation of heat transfer in gas turbines is a long-lasting and still an active subject ofresearch due to its tremendous importance. LÄS MER
23. Experimental and Theoretical Study of Rack Storage Fires
Sammanfattning : A theoretical and experimental study of rack storage fires and responsiveness of sprinklers is presented. Free-burn tests with non-combustible and combustible material were carried out in reduced scale with verification in large scale. LÄS MER
24. Computational Analysis of Gas Flow and Heat Transport Phenomena in Ducts Relevant for Fuel Cells
Sammanfattning : The thesis concerns modeling, simulation and numerical analysis of heat and mass transport, and fluid flow in ducts of both solid oxide fuel cells (SOFCs) and proton exchange membrane fuel cells (PEMFCs). The unique fuel cell boundary conditions (thermal, mass) for the flow ducts in fuel cells are identified and applied. LÄS MER
25. Exhaust Heat Utilisation and Losses in Internal Combustion Engines with Focus on the Gas Exchange System
Sammanfattning : Exhaust gas energy recovery should be considered in improving fuel economy of internal combustion engines. A large portion of fuel energy is wasted through the exhaust of internal combustion engines. Turbocharger and turbocompound can, however, recover part of this wasted heat. LÄS MER
