WebbIn this study, finite element and finite difference methods were used for numerical calculations. The law of slurry diffusion in the inclined plane cracks is summarized in this study. Further, the equation describing the diffusion of slurry with time-varying viscosity in the plane fracture with dip angle was derived, and the mathematical model of slurry … Webb22 nov. 2011 · Maintaining viscosity high enough to carry cuttings from the bore is critical in maintaining penetration rates. Too little viscosity will allow cuttings to fall out of the slurry and be deposited behind the drill …
Slurry Rheology - an overview ScienceDirect Topics
WebbApparent viscosity of CWS of lignite decreased obviously by method I, and it had a further decreased by method II. And the results of contact angle showed that there was an obvious increase in hydrophobicity of lignite particles, which were corresponding to the decrease of apparent viscosity of CWS of lignite. Webbviscosity of the slurry under given solids fractions were predicted using the maximum solids fraction φm determined from the ηr-φ relationship. Also the effect of particle size … biserica herastrau
