Abstract: The double-gyre circulation, formulated in terms of the quasigeostrophic equations, has a symmetry about the basin midlatitude (y ? ?y, ? ? ??), which is absent in a formulation based on the shallow-water equations. As a ...

Abstract: In core gas turbines relatively cold air is purged through the hub gap between the stator and rotor in order to seal the disk space against flow ingestion from the main annulus. Although the sealing mass flow rate is ...
