Abstract. In this paper, we describe the application of the discrete element method
to solve a specific electrodynamic problem, namely, to study the refractive
properties of the flow that drags the finely dispersed impurities placed in it.
The study of the problem consists of a number of full-scale tests and setting
up a target computational experiment on the model using the discrete element
method to obtain data for verification of a subsequent laboratory study. The
main emphasis in this work is done on the indicated experiment, whereas
modeling by the discrete element method is proposed to be used as a possible
tool of the functional cycle of approbation of theoretical provisions. The
study is carried out on the example of an iron powder with known parameters
placed in a moving liquid. Refractive properties are studied by the waveguide
method. A model of dynamic modeling, a connection of the method of discrete
elements with the finite element method, and the setting up of physical
simulation conditions are proposed.
Key words: discrete
element method, dynamic modeling, particles, flow, electromagnetic refraction.
