The animation illustrates how random and directed movements of particles lead to different spatial distributions. A random movement is called diffusion, a directed movement is called drift. Drift and diffusion are crucial for understanding solar cells. Free charge carriers are generated in a semiconductor material when it is exposed to light. These charge carriers move… Read More »
The interactive animation shows the forces that act on the rotor of a wind turbine (and can be visualised in the rotor plane). These forces must be taken into account when designing wind turbines. The amount of tangential force can be varied using a controller. The tangential force results from the lift force that is… Read More »
The animation shows how the ideal rotor blade shape of a wind turbine can be calculated. Various parameters are taken into account, such as the desired number of rotor blades or the average wind speed at the installation site. Several parameters can be changed in the animation. The result is displayed both as a curve… Read More »
