Engineering Model to Calculate Mass Flow Rate of a TwoPhase Saturated Fluid Through An Injector Orifice Brian J. Solomon ... ENGINEERING MODEL TO CALCULATE MASS FLOW RATE OF A TWOPHASE ... Saturated liquid and vapor compressibility factors for CO 2 and N 2O . . . .7 Comparison of CO
This calculation depends, in part, on the gas and liquid flow rates but also on the standard Fanning (singlephase) friction factor chart. When evaluating the Fanning friction factor, there are many ways of calculating the Reynolds number depending on how the density, viscosity, and velocity of the twophase mixture are defined.
Physicists recognize three types of latent heat, corresponding to the changes of phase between solid, liquid, and gas: The latent heat of fusion, L f . This is the heat per kilogram needed to make the change between the solid and liquid phases, as when water turns to ice or ice turns to water.
diagram, the molten phase goes to a glass or, if cooling is slow, the C3A crystallizes out and in extreme cases the Alite dissolves back into the liquid phase and reappears as secondary Belite. Alkali sulfates condense out as a separate phase during the cooling process but these are not shownin
The calculation of the cement phases percentages is based on the research work, Calculation of the Compounds in Portland Cement, published by Bogue in 1929 .The usage of high sulphur fuels, industrial wastes, and tires changes completely the working condition of Bogue because the assumed phase compositions may change.
Additional uncertainty in the 0 5 8 results from the calculation of the Correction for the Pressure of the Liquid ( % É Å).% É Å is based on the difference between the liquid's measured pressure and its saturation pressure.
If their content is too high, the resulting liquid phase will be too much, which will make boring and easy to bulk up and affect the operation; if If the content is too low, the amount of liquid phase is too small, which makes firing difficult, and the clinker is easily "pulverized."
sizing of relief valves for twophase flow in the bayer process countercurrent flashing heat exchange with the incoming spent liquor and the potential then exists for the hot slurry to flow onto downstream pressure vessels.
cosity and increase the surface tension of the clinker liquid phase should solve the problem. One way to do this is by increas ing the alkali content of the clinker, per haps by the addition of feldspar to the raw mix, as this has the required effect on the flux viscosity.
clinker nodules are formed by agglomeration due to capillary forces of the liquid. The microscope is used to observe features such as clinker phase size, morphology, abundance, and distribution.
SULFATES IN PORTLAND CLINKER AND CEMENT Taylor Maundry Bank, Lake Road, Coniston, Cumbria LA21 8EW, UK ... calculation of this distribution from the bulk composition of the clinker; ... case [1,4], which was a single clinker, the content of the alite had barely decreased after 10 minutes' hydration, but that of the anhydrite had ...
The Bogue calculation can only be a first estimation because it does ... Generally, the clinker phase comp osition is more complex than ... Low alkali content. High alkali content. cubic. orthorhombic. less reactive. more reactive modification (with potassium) slower hydration.
With increasing amounts of phosphorus pentoxide in the raw material of clinker, phosphorus was shown to primarily enter the belite phase and to a lesser extent the alite phase (Gutt, 1963; Nastac et al., 2007; Stanek and Sulovsky, 2009).
The model describes the clinker burning process from the kiln meal feed to the discharge of clinker from the cooler, and consists of individual models for preheater, calciner, gas .
The content of the clinker (having subtracted the gypsum in step 1, if the oxide composition is for a cement) can be distributed in a few different phases, including K 2 SO 4, Na 2 SO 4, Ca 2 K(SO 4) 3, and as impurities in the cement minerals.
GasLiquid Separators Sizing Parameter In the December 2014 tip of the month (TOTM) [1], we discussed troubleshooting of gasliquid separators for removal of liquids from the gas stream leaving the separator. There are two methods for sizing gasliquid separators: 1. Droplet settling theory method, 2. SoudersBrown approach.
The approach suggested by Hall (1992) was to model the threephase stratified flow using a threefluid model (in a similar way to the Taitel and Dukler twofluid method for gasliquid flow) and to use the holdup obtained from this method to calculate the stratified to slug transition.
