21. Metamodel-Based Multidisciplinary Design Optimization of Automotive Structures
Sammanfattning : Multidisciplinary design optimization (MDO) can be used in computer aided engineering (CAE) to efficiently improve and balance performance of automotive structures. However, large-scale MDO is not yet generally integrated within automotive product development due to several challenges, of which excessive computing times is the most important one. LÄS MER
22. Ventilation Flow Field Characteristics of a Hydro-Generator Model- An experimental and Numerical Study
Sammanfattning : Hydro-generators are complex machines used to convert the mechanical energy of the water turbine into electrical energy. Electromagnetic and mechanical losses accompany this energy conversion process which will cause heat generation and temperature increase. Cooling systems are needed to remove this excess heat from hydro-generators. LÄS MER
23. Studies on Diesel sprays under non-reacting and reacting conditions
Sammanfattning : Methods for reducing engine-out emissions are urgently needed to mitigate climate change and air pollution. In diesel engines, the quality of fuel-air mixing and the subsequent combustion process strongly affect fuel efficiency and engine-out emissions. LÄS MER
24. Exergy Evaluation of Engine Operations : Combustion Process to Exhaust Flow
Sammanfattning : Transitioning the transport sector to clean energy sources is crucial for mitigating greenhouse gas emissions and achieving carbon neutrality. A collaborative solution, combining both electric vehicles and combustion engines using renewable fuels, may prove more effective than competitive ones. LÄS MER
25. Detection of blade icing and its influence on wind turbine vibrations
Sammanfattning : Wind turbine installations in extreme conditions like cold climate have increased over thelast few years and expected to grow in future in North America, Europe, and Asia regions due to good wind resources and land availability. Their installed capacity could reach 186 GW by the end of 2020. LÄS MER
