In this paper theory on cylinder and wind turbine wakes have been studied, and experimental work on the wake behind a wind turbine have been carried out in the Fluids engineering laboratory at NTNU.The objective of this ...

In order to decrease the average costs of energy, wind turbines are arranged in wind farms where aerodynamic interactions between the turbines occur. When planning and optimizing the performance of a wind farm, these ...

Målet i denne rapporten er å undersøke, foreslå og utvikle varmesystemer basert på gjenvinning av spillvarme, med formålet å levere varmeenergi til byggene på CERNs campusområdet mer effektivt og mer miljøvennlig. De ...

Waste amounts are growing with increasing wealth and population. To curb this trend and reduce adverse environmental impacts, food waste reduction has been sat on the political agenda, together with ambitious material ...

When a liquid droplet is deposited onto a heated surface, evaporation occurs. If the temperature of the surface is sufficiently high, bubbles are released from activated nucleation sites, making the heat transfer more ...

The planning and analysis of a laboratory set-up for examining the behaviour of water waves in the presence of sub-surface shear is presented in the following work. Water waves propagate on shear currents in many important ...

Super-repellent surfaces are relevant for several practical applications, such as water collection and self-cleaning and anti-icing surfaces. However, designing surfaces that can maintain their super-repellency when the ...

We consider systems of hyperbolic balance laws governing flows of an arbitrary number of components equipped with general equations of state. The components are assumed to be immiscible. We compare two such models: one in ...

Extreme waves, also known as rogue waves, have much larger heights than surrounding waves, which are of great danger to ships and coastal structures. A subsurface shear current is able to change the properties of the surface ...
