	Fluid bearing - Wikipedia, the free encyclopedia
		Fluid bearings, also called fluid dynamic bearings or hydrostatic or gas bearings, are bearings which support load on a thin layer of liquid or gas.
		Fluid Bearings use a thin layer of liquid or gas fluid between the bearing faces, typically sealed around or under the rotating shaft.
		Ice skates are a hydrodynamic fluid bearing where the skate and ice are separated by a layer of water caused by entropy (formerly thought to be caused by pressure-induced melting; see ice skating for details).

		The working fluid thermodynamic cycle simulation program, referred to as GEO 1, was developed by writing an executive program which utilizes subroutines from a previously developed thermodynamic behavior prediction program (2), referred to herein as HSGC.
		The initial estimate of the working fluid pressure at the condenser inlet is chosen to be the dew point pressure at the minimum possible temperature consistent with the input condenser minimum approach temperature constraint.
		After the working fluid pressure at the condenser exit is calculated, the working fluid temperature at the condenser exit is calculated to be the bubble point temperature at this exit pressure, and if the minimum approach temperature criterion is violated, the turbine exit pressure is increased and step 5 is repeated.

		The working fluid leaves the compressor as a hot, high pressure gas and flows into the condenser.
		By the time the working fluid leaves the condenser, its temperature has almost dropped back down to the outdoor temperature but it is now a liquid rather than a gas.
		As it evaporates, it extracts heat from the air around the evaporator because that heat is needed to separate the molecules of the working fluid.

	Influence of Dynamic Changes in Chemical and Microbiological Characteristics on Metal Working Fluid Toxicology (Site not responding. Last check: 2007-10-16)
		The major focus of the study was to evaluate the time course of change in the chemical and microbial characteristics of metal working fluid, and to determine whether these chemical or microbial components of semi-synthetic metal working fluid are responsible for the pulmonary effects associated with low dose occupational exposure.
		The significantly greater increase in PMNs in guinea pigs exposed to the in-use fluid suggested that components of the dynamically changing in-use metal working fluid were capable of producing inflammation in the mammalian respiratory system.
		Importantly, the study demonstrated that as the chemical and biological condition of the in-use metal working fluid matched that seen in the pre-DCR sample, a return to an inflammatory potential of the in-use samples occurred.

	Working Fluids for Increasing Capacities of Heat Pipes
		The surface tensions of all of the working fluids heretofore used in heat pipes decrease with temperature.
		In the case of a traditional working fluid, the decrease in surface tension with temperature causes a body of the liquid phase of the working fluid to move toward a region of lower temperature, thus preventing the desired spreading of the liquid in the heated portion of the heat pipe.
		For example, as a substitute for ammonia, which is the working fluid in some heat pipes, one could use a solution of ammonia and an ionic surfactant.

		The results of the vapor pressure measurements on the Q2 fluid were provided in graphical format as well as in the Antoine type equation by determining various coefficients.
		According to these findings the Q2 fluid seems to be a good potential candidate for use in a conventional NH3/H2O absorption heat pump as well as advanced systems.
		At the present time, we feel that the higher viscosity and density, resulting in lower mass transfer and higher pumping work, due to the salts constituent in the Q2 fluid may be a trade-off compared to NH3/H2O.
