Представлена гибридная математическая модель осесимметричной плазменной ловушки, основанная на кинетическом описании для ионной компоненты плазмы и приближении МГД для электронной компоненты. На основе гибридной модели разработан двумерный алгоритм для изучения динамики разлета инжектируемых частиц в поле ловушки. Движение ионной компоненты рассчитывается по методу частиц в ячейках, для расчета магнитного поля и электронной компоненты плазмы используются конечно-разностные схемы. На основе разработанного алгоритма создан комплекс программ для исследования механизмов формирования самосогласованной структуры магнитного поля ловушки. A hybrid mathematical model of an axisymmetric plasma trap based on the kinetic description for the ion component of the plasma and the MHD approximation for the electronic component is presented. On the basis of the hybrid model, a two-dimensional algorithm is developed to study the dynamics of injected particles in the trap field. The motion of the ion component is calculated by the particle-in-cell method. Finite-difference schemes are used to calculate the magnetic field and the electron component of the plasma. On the basis of the developed algorithm, a program code is created to study the mechanisms of the self-consistent magnetic field structure formation.

Abstract In the paper, the authors describe the method of reduction of a model of rotor system. The proposed approach makes it possible to obtain a low order model including e.g. non-proportional damping or the gyroscopic effect. This method is illustrated using an example of a rotor system. First, a model of the system is built without gyroscopic and damping effects by using the rigid finite element method. Next, this model is reduced. Finally, two identical, low order, reduced models in two perpendicular planes are coupled together by means of gyroscopic and damping interaction to form one model of the system. Thus a hybrid model is obtained. The advantage of the presented method is that the number of gyroscopic and damping interactions does not affect the model range
