Nonlinear dynamic analysis of bi-directional porous aero-thrust bearing systems
Advances in Mechanical Engineering, 2017 For some years, bi-directional porous aero-thrust bearing systems have been receiving much attention. They are now applied extensively where there is a need for rigidity in high-precision instruments and mechanisms that run at high speed.

The Utilization of the Microflora Indigenous to and present in Oil-Bearing Formations to Selectively Plug the More Porous Zones Thereby Increasing Oil Recovery During Waterflooding [PDF]
, 1996 This project was designed to demonstrate that a microbially enhanced oil recovery process (MEOR), developed in part under DOE Contract No. DE-AC22-90BC14665, will increase oil recovery from fluvial dominated deltaic oil reservoirs. The process involves stimulating the in-situ indigenous microbial population in the reservoir to grow in the more ...

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1993 The frictional characteristics of a porous bronze bearing are experimentally studied in hydrodynamic and mixed lubrication regimes. The results show that the relationships between the coefficient of friction μ and Sommerfeld number S obtained for a range of oil-feed pressure and shaft speed could be rearranged using dimensionless oil-feed pressure ps ...

The Utilization of the Microflora Indigenous to and Present in Oil-Bearing Formations to Selectively Plug the More Porous Zones Thereby Increasing Oil Recovery During Waterflooding [PDF]
, 1998 The objective of this work is to demonstrate the use of indigenous microbes as a method of profile control in waterfloods. It is expected that as the microbial population is induced to increase, that the expanded biomass will selectively block the more permeable zones of the reservoir thereby forcing injection water to flow through the less permeable ...
