Heat Transfer at the Bottom of a Cylindrical Vessel Impinged by a Swirling Flow from an Impeller in a Draft Tube [PDF]
Chemical and Biochemical Engineering Quarterly, 2017 Heat transfer at the bottom of a cylindrical vessel impinged by a flow with tangential velocity component generated by an axial-flow impeller in a draft tube was measured using the electrodiffusion experimental method.

Invariants in toroidal and tangentially geostrophic frozen-flux velocity fields [PDF]
Geophysical Journal International, 1996 We derive two new types of invariant that must be obeyed by the radial magnetic field at the core-mantle boundary if the hypothesis of frozen flux is valid and the fluid motion is either toroidal or tangentially geostrophic there. These general invariants incorporate specific invariants that are already known and can, in principle, be tested using ...

Formulation of the tangential velocity slip problem in terms of variational inequalities
, 2014 This contribution deals with a modelling of the tangential velocity slip problem in terms of variational inequalities. In particular, various technical situations for which the slippage problem appears to play an important role are first reviewed.

On the direction of Coriolis force and the angular momentum conservation
Revista Brasileira de Ensino de FísicaThis paper presents a qualitative analysis of the Coriolis force direction using the conservation of angular momentum and comparing it with quantitative calculation. In order to understand the implications of the theoretical expression for Coriolis force,

Shape of the Galactic Orbits in Clusters
, 1998 A kinematical analysis applied to a sample of galaxy clusters indicates that the differences between the velocity distribution of elliptical and spiral galaxies are associated with the shape of their orbit families.
