The Savonius vertical axis wind turbine is simple in structure, has good starting characteristics, relatively low operating speeds, and an ability to accept wind from any direction, although it has a lower efficiency than some other vertical axis wind turbines. So far a number of experimental...

Numerical simulation of wake losses is a fundamental step towards the optimization of the exploitation of the renewable wind energy potential especially in off-shore conditions or in coastal areas.

In the museum environment, the temporal stability and the spatial uniformity of the indoor microclimatic parameters are necessary primarily for the correct artwork conservation and then for the occupant thermal comfort. Therefore, a HVAC system is usually necessary.
