Abstract: For the anelastic or pseudoincompressible system, the diagnostic continuity equation is the constraint filtering sound waves. Hamiltonian fluid dynamics considers the pressure force as the reaction force to this constraint. ...

Abstract: Experiments were performed in a rotating, differentially heated annulus, with and without bottom topography of azimuthal wavenumber 2. Both water and a viscous glycerol-water mixture were used as a working fluid. In one ...
