6. Model Studies of Surface Waves and Sediment Resuspension in the Baltic Sea
Sammanfattning : Wave heights and periods of surface waves in the Baltic Sea have been modelled for a two-year period (1999-2000) with the wave model Hypas on an 11x11-km grid scale. There is a clear seasonal variation with higher waves during winter and lower during summer. LÄS MER
7. Wind power wake modelling : Development and application of an actuator disc method for industrial utilization
Sammanfattning : As a wind turbine extracts energy from the wind it creates a region downstream where the wind velocity is decreased and the urbulence intensity is increased, this region is commonly called the wake region. Today’s wind farms include a large number of wind turbines position in tight layouts. LÄS MER
8. Simulations And Experiments Of Plasma-Induced Effects In Silicon Detectors
Sammanfattning : When an atomic nucleus undergoes fission, two fragments with different mass and kinetic energy are emitted. The highly unstable fission fragments (FFs) evaporate prompt neutrons soon after the nucleus splits. LÄS MER
9. Hydrokinetic Resource Assessment : Measurements and Models
Sammanfattning : The conversion of kinetic energy in water currents into electricity has gained great attention the past years. The conversion systems are stand-alone units that typically consist of a turbine, driven by the water stream, with a generator connected to it. LÄS MER
10. Pulsed Neutron Activation for Determination of Water Flow in Pipes
Sammanfattning : In a Pulsed Neutron Activation (PNA) flowmeter neutron induced activity is used to measure water flow in pipes. The water in the pipe is bombarded with neutron pulses which introduce activity into the pipe. The activity is then transported and mixed with the flow. LÄS MER
