Saturated, boiling

Heat transfer characteristics for saturated boiling were considered by Yen et al. (2003). From this study of convective boiling of HCFC123 andFC72 in micro-tubes with inner diameter 190, 300 and 510 pm one can see that in the saturated boiling regime, the heat transfer coefficient monotonically decreased with increasing vapor quality, but independent of mass flux. 

Hetsroni et al. (2003b, 2003, 2005a,b) observed the explosive saturated boiling regime in micro-channels, which exists before the annular flow regime. The test...

To take into account that the constant Cd in Eq. (2-59) is really dependent to a significant extent on the boiling pressure, Cole and Rohsenow (1969) proposed a modified correlation that also appears to work quite well for a large variety of ordinary liquids for saturate boiling ... 

A combination of two separate energy-transfer mechanisms were considered for <7"ub a conduction mechanism as in saturation boiling, and a sensible heat transport mechanism. 

A general expression for average void fraction in an adiabatic two-phase flow or in saturated boiling was suggested by Zuber and Findlay (1965). Defining the local superficial velocities, VSG(= Qc/A) and VSL (= QJA), as volumetric flux densities, they assumed the velocity and void distributions to be... 

Extension of A.R.S. CHF correlation to nonuniform heating. To extend the correlation described in the previous section, the saturation boiling length hypothesis is followed. By means of a straightforward transformation, Eq. (5-133) becomes...

Low saturation (boiling) pressure at high temperature—to minimize the pressure vessel and piping costs. 

The saturated hydrocarbon fractions contain traces of sulfur. The gas-solid chromatography of the Lloydminster saturates boiling in the range of the C2s normal alkane, using a Melpar flame photometric detector, shows that the sulfur compounds are retained much longer than the hydrocarbons. This is typical for alkyl sulfides. 

The saturates boiling above 470°F were analyzed by MS and appear to contain alkanes but predominantly cycloparaffins. The alkanes appearing in these liquids may not be part of the coal network but may simply be embedded in it. The primary coal structure is generally believed to be formed of small aromatic units held together by short links, mainly...
