    • Abstract

  • The theoretical model of the specific surface area for the porous media sintered by the spherical powders is established by discrete modeling software EDEM, considering the actual average coordination number and the impenetrability parameter, based on the theory of spheres random stacking model. Compared with the conventional model, the established model has a wider range of applications. Taking the actual capillary rise test as the empirical object, the capillary rise height is predicted by coupling Bernoulli equation with the established model, and the prediction results show the agree with the experimental results, indicating that the established model has the good accuracy and application value.
