Abstract

The invention discloses a calculation method for exclusion volume of a convex core-shell structure body. The method comprises the following steps of determining a particle geometric model of a core, and defining the sizes of particles of the core by adopting an equivalent diameter; calculating a particle mean caliper diameter of the core; calculating the volume of the convex core-shell structure body; calculating a surface area of the convex core-shell structure body; calculating a mean caliper diameter of the convex core-shell structure body; and calculating the exclusion volume of the convexcore-shell structure body. The method can accurately calculate the exclusion volume of the convex core-shell structure body with core particle types of ellipsoids, spherical cylinders and regular polyhedrons, gets rid of a technical constraint that a conventional theoretical method only aims at simple spherical particles, and solves the problems that a numerical simulation method can perform study only for specific particles and is low in efficiency and difficult in simulation precision guarantee, so that the calculation method for the exclusion volume of the convex core-shell structure bodyis more universal and representative.

Description

technical field [0001] The invention relates to a method for calculating the repelling volume of a convex core-shell structure, and belongs to the technical field of microcosmic theory and numerical experiment of discrete media. Background technique [0002] The exclusion volume refers to the space that other particles in the space cannot occupy after a hard core particle occupies a certain space. This concept was proposed by Werner Kuhn in 1934, and he himself did a lot of groundbreaking basic work. At the same time, many theoretical works have confirmed that there is a quantitative relationship between the physical properties of materials such as the percolation threshold, the packing density of particles, and the exclusion volume of particles. The current research and discussion on spherical particles has been relatively sufficient. For example, the repelling volume of monodisperse hard spheres is 8 times its own volume, and its packing density has been confirmed in theo...
