21. Optimization of confluent jets ventilation with variable airflow
Sammanfattning : In recent years, applications of confluent jets for design of ventilation supply devices have been widely studied. Similarly, numerous studies have been made on the potential and application of variable air volume (VAV) in order to reduce the energy demand of ventilation systems. LÄS MER
22. Modelling the Role of Nuclear Power and Variable Renewables in Climate Change Mitigation
Sammanfattning : As the number of people on Earth and our energy needs have increased the system for providing this energy has become ever more complex and complicated and thus the need for more systematic understanding of it has grown. However, change in energy system is slow and many of the challenges that we face such as mitigating climate change need global solutions. LÄS MER
23. The roles of transmission and distribution networks in integrating variable renewable electricity generation
Sammanfattning : Emission reduction targets, together with other factors, such as security of supply, are driving the expansion of variable renewable energy sources for electricity generation, mainly solar and wind power. Trading across the transmission grid is an important measure to handle the increased variability and to balance supply with demand. LÄS MER
24. Control of variable speed wind turbines in a broad range of wind speeds
Sammanfattning : .... LÄS MER
25. The Influence of Residual Stresses on Constant and Variable Amplitude Fatigue Behaviour of Steel
Sammanfattning : Subjected to dynamic loading, truck components are exposed to variable amplitude fatigue. The fatigue life of components is to a large degree controlled by the behaviour of the surface zones. LÄS MER
