Storage Stability of Ceramic Slurries for Gelcasting
Key Engineering Materials, 2007In the industrialization of gelcasting, storage of ceramic slurry has been one of the key problems that must be solved. Except for sedimentation of ceramics particle, solidification properties of slurries were also affected after long-term storage. In this article, some factors in the process of slurry were discussed, and corresponding solution methods

Boiling‐slurry reactor: Feasible operation and stability
AIChE Journal, 1998AbstractIn this study the feasible operation and stability of a special boiling‐slurry reactor (BSR), in which a single exothermic chemical reaction occurs, are determined. Its feed consists of a nonvolatile liquid reactant dissolved in an inert solvent and gaseous reactants, while the effluent consists only of gaseous components.

The face stability of slurry-shield-driven tunnels
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1994Abstract During the excavation of a tunnel through soft water-bearing ground, a temporary support is often required to maintain the stability of the working face. In a slurry shield, this support is provided by a pressurized mixture of bentonite and water. Slurry-shield tunnelling has been applied successfully worldwide in recent years.

Landslide Stabilization Using High Strength Aggregate-Cement Slurry
Geo-Congress 2013, 2013Most large landslides are repaired via some combination of mass grading, structural restraint systems, and/or dewatering. A deep-seated landslide occurred in Dana Point, California, in 2005 that resulted in the destruction of one home and the red-tagging of three others.

Stability of Slurry Trenches with Inclined Ground Surface
Journal of Geotechnical and Geoenvironmental Engineering, 2013AbstractA method for assessing stability of slurry trenches within an inclined ground surface is presented using the Coulomb-type force equilibrium method. The influence of ground surface inclination on trench stability and angle of critical failure surface is investigated via parametric studies on an example trench.

Analytical Solutions for Stability of Slurry Trench
Journal of Geotechnical and Geoenvironmental Engineering, 2004Coulomb-type force equilibrium analyses are presented for general two- and three-dimensional stability of a slurry-supported trench. Analytical solutions are derived for the factor of safety and critical failure plane angle in each case for drained effective stress and undrained total stress conditions.

Closed-Form Solution for Stability of Slurry Trenches
International Journal of Geomechanics, 2017AbstractThis paper presents a variational limit equilibrium closed-form solution for the stability of slurry-supported trenches in cohesive soil, frictional cohesive soil, and cohesionless soil. Study results indicate that the critical slip-surface geometry is either planar or log spiral. The normal stress distribution, which indicates the likely depth

Slurry trench stability-theoretical and practical aspects
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1974THIS ARTICLE IS CONCERNED WITH THE PRACTICAL ASPECTS OF A NUMBER OF FACTORS AFFECTING SLURRY TRENCH STABILITY. THE AUTHOR FIRST CONSIDERS MUD PRESSURE, WHICH IS A FUNCTION OF MUD DENSITY (INCLUDING CONTAMINANTS), POINTING OUT THAT THE USE OF WEIGHTED MUDS MAY REMEDY EXCAVATION PROBLEMS, BUT AT THE SAME TIME CAUSE DIFFICULTIES IN CONCRETING.

Analysis of the physical stability of PCM slurries
International Journal of Refrigeration, 2013Microencapsulated phase change material slurry (mPCM slurry) is a latent heat storage fluid in which the PCM microparticles have been dispersed in water. One of the main issues to be tackled is its lack of physical stability, since stratification problems tend to occur. Generally, an unstabilization process in PCM slurries can take weeks or even months.

Sedimentation Stability and Rheology of Coal Water Slurries
Coal Preparation, 1997Sedimentation of coal particles should be avoided during the transportation of coal water mixtures (CWMs) by sea in tankers. The sedimentation of coal particles under shear flow plays an important role in the stability of CWMs. It is important to understand how the theological characteristics of CWMs are related to the sedimentation stability.
