The results show that (1) as the temperature increases, the overall trend of rock permeability decreases, which is mainly related to the thermal expansion of rock particles. In addition, the higher the temperature, the greater the gravel outflow. (2) The critical pressure for pore closure in...
Preparation of Foamed Hydrophobic Magnesium Oxychloride Cement Test Block In this study, the initial raw material ratio of magnesium oxychloride cement was determined to be MgO:MgCl2:H2O = 6.5:1:13 (molar ratio) [20], and MgO was calculated as α-MgO. Firstly, we pre-hydrolyzed the ...
In most cases, the measurements support the calculations; hence, the model is suited to describe and predict basic mechanisms of phonation and the inertial effects caused by a vocal tract. Keywords: analytical vocal fold model; fluid–structure interaction; vocal tract inertia 1. Introduction ...
