... Here, < >0 denotes average over f0 . The divergence of the tensors in (44) and (45) means to take the divergence of each row of the tensor as a vector element. It is worth noticing that the constraint f1 f0 , which is the basis of the Legendre polynomial expansion approach in [?] and the perturbed ...

Kinetic Energy
... More Energy Transfer • High speed winds are used to do work on the blades of a turbine at the so-called wind farm. • Mech. Energy from the air gives the air particles the ability to apply a force to the blades. • As the blades spin, their energy is subsequently converted into electrical energy (a n ...
