Hydrodynamic modelling of hydrostatic magnesium extrusion [PDF]
, 2006 Wilson’s hydrodynamic model of the hydrostatic extrusion process is extended to meet the geometry found on residual billets. The transition from inlet\ud to work zone of the process is not considered sharp as in the model of Wilson but as a rounded edge,

Flow of Lubricating Greases in Centralized Lubricating Systems
Bulletin of The Japan Petroleum Institute, 1968 This work was undertaken to determine the effects of the composition of lubricating greases on their flow behavior in centralized lubricating systems and to obtain criteria for the selection of suitable greases for these systems. Flow properties of several lubricating greases of various composition were measured by the ASTM apparent viscometer and a ...
