Firstly, the mathematical model of the electro-hydraulic servo system …
Introduction to LSF Hydraulic Classifier. LSF hydraulic classifier is part of the family of hindered settling classification equipments. It adopts the mechanism of "layer flow high shear rate", which solves the problem that traditional technology cannot adapt to the change of feed particle size, resulting in the loss of fine material recovery.
The hydraulic conductivity of porous media, as a very challenging problem, finds its roots in historical work of Darcy [] with applications in many disciplines [6, 12, 29].Afterwards, a variety of methods were developed to study the hydraulic conductivity in granular porous media, mainly for isotropic materials; among which are the empirical …
The hydraulic conductivity of a granular porous medium depends on parameters such as the porosity, particles shape and fluid viscosity. Although other factors may affect the permeability of the granular matrix, their effects are often insignificant while their measurements are sometimes very difficult. There are many experimental studies …
