Stability of multilayer extrusion of viscoelastic liquids
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1990-05)
A linear stability analysis of multilayer plane Poiseuille flow of Oldroyd-B liquids with shear rate dependent viscosities is performed for an arbitary number of layers. Asymptotic solutions at long wavelengths and numerical ...
The sequential-clustered method for dynamic chemical plant simulation
(Elsevier, 1990-02)
We describe the design, development and testing of a prototype simulator to study problems associated with robust and efficient solution of dynamic process problems, particularly for systems with models containing moderately ...
Molybdenum nitride catalysts : I. Influence of the synthesis factors on structural properties
(Elsevier, 1994-03)
Effects of the synthesis parameters on the structural properties of molybdenum nitride catalysts, prepared by the temperature-programmed reaction of MoO3 with NH3, have been examined. Molybdenum trioxide was heated in ...
Electrolyte-moderated interactions in water/oil microemulsions
(Elsevier, 1984-11)
Interactions between the disperse phase droplets of water-in-oil (W/O) microemulsions of Aerosol-OT are profoundly affected by the addition of small amounts of electrolyte. We find that the effect of added electrolyte in ...
Optimal control of a continuous flow stirred tank chemical reactor
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1970-11)
The time optimal control problem for jacket cooled continuous flow stirred tank reactor (CSTR) with an exothermic, irreversible, second-order, homogeneous, liquid-phase reaction (the saponification of ethyl acetate) was ...
Quasi-elastic light-scattering investigation of microemulsions
(Elsevier, 1980-09)
Quasi-elastic light scattering was used to investigate W/O microemulsions of heptane-AOT-(bis(2-ethylhexyl)sulfosuccinate sodium salt)-water and W/O and O/W microemulsions of hexadecane-SDBS (sodium dodecyl benzene ...
Acidization III--The kinetics of the dissolution of sodium and potassium feldspar in HF/HCl acid mixtures
(Elsevier, 1975-11)
The dissolution of a potassium and a sodium feldspar in hydrochloric-hydrofluoric acid mixtures was studied in a rotating disk system at 25 and 100[deg]C under a pressure of 40 psig. Under these conditions, the dissolution ...
