6. Experimental Studies of Effusion Cooling
Sammanfattning : The desire to increase the efficiency of jet engines, has led to an increase in the temperature in the combustion chambers and in the turbine stage. There is thus an interest in efficient cooling methods. Film cooling and effusion cooling are often used where there is a great heat load. LÄS MER
7. Structure determination of beam sensitive crystals by rotation electron diffraction : the impact of sample cooling
Sammanfattning : Electron crystallography is complementary to X-ray crystallography. Single crystal X-ray diffraction requires the size of a crystal to be larger than about 5 × 5 × 5 μm3 while a TEM allows a million times smaller crystals being studied. This advantage of electron crystallography has been used to solve new structures of small crystals. LÄS MER
8. On Optimization of Injection Molding Cooling
Sammanfattning : .... LÄS MER
9. Modeling of Electron Cooling : Theory, Data and Applications
Sammanfattning : The Vlasov technique is used to model the electron cooling force. Limitations of the applicability of the method is obtained by considering the perturbations of the electron plasma. LÄS MER
10. High Performance Cooling of Traction Brushless Machines
Sammanfattning : The work presented in this thesis covers several aspects of traction electric drive system design. Particular attention is given to the traction electrical machine with focus on the cooling solution, thermal modelling and testing. LÄS MER
