On the extension of the model of matrix acid stimulation to different sandstones
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1976-07)
A model was developed for the acidization of various sandstone cores which successfully describes the flow and reaction in the porous media during acidization. A comparison of the experimental results of various investigators ...
Solubility inversion effects on diffusion from collapsing bubbles
(Elsevier, 1971-09)
This work discusses the dissolution of gas bubbles in liquids subjected to a sudden pressure surge, as well as lending insight to studies on rectified diffusion. The bubble growth rates for rectified diffusion under ...
In defense of the Crank-Nicolson method
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1970-05)

The macroscopic yield behaviour of polymers
(Kluwer Academic Publishers; Chapman and Hall ; Springer Science+Business Media, 1973-02)
A yield criterion, not previously compared with the actual macroscopic behaviour of polymers, is herein compared with the pressure-modified octahedral shear stress criterion earlier suggested by others. This new relation, ...
Macrosonics in industry : 4. Chemical processing
(Elsevier, 1975-01-01)
Acoustic irradiation can result in increased inter-phase mass and heat transfer rates. The second-order acoustic effects of cavitation, interfacial instability, radiation pressure and acoustic streaming are responsible for ...
Acidization--II. The dissolution of calcite in hydrochloric acid
(Elsevier, 1975-08)
The dissolution of calcite in hydrochloric acid was studied with the aid of a rotating disk system at 800 psig in the temperature range -15[middle dot]6-25[deg]C. At 25[deg]C the dissolution process is mass transfer limited ...
Acidization--IV : Experimental correlations and techniques for the acidization of sandstone cores
(Elsevier, 1976)
The experimental variables that affect the acidization of sandstone cores in a permeameter are discussed. It was found that as HCl/HF acid mixtures are injected into porous sandstone cores a reaction front between selective ...
Annealing effects of polymers and their underlying molecular mechanisms
(Elsevier, 1976-04)
This paper indicates that changes in chain mobility, heat capacity, WAXS crystallinity, SAXS long period, SAXS peak intensity, specific volume and morphology as a function of increasing temperature, occur in three fairly ...
