A research team at City University of Hong Kong (CityU) has discovered a new type of sound wave: the airborne sound wave vibrates transversely and carries both rotation and orbital angular momentum ...

The control of small structures and fast modes needs not only more accurate values in the commonly used dimensions (, u, T, P), but also, in fact more essentially, the controls from more dimensions.

The compressible Navier-Stokes equations form the cornerstone of fluid dynamics, describing the motion of viscous compressible fluids under conservation of mass, momentum and energy. By incorporating ...
