โœฆ Synopsis


A hybrid mathematical model is proposed for describing the non-stationary processes in plasma-optical systems ,in which the dynamic behaviour of the heavy components of the plasma medium (the ions and neutral atoms) is described by kinetic equations taking account of ionization processes, while the dynamic behaviour of the electronic component is described at the hydrodynamic level. To solve the resulting system of integrodifferential equations, a conservative numerical algorithm is proposed, based on the conservative version of the 'coarse particles' method.

In the present paper we consider the construction and study of mathematical models of the problems of plasma optics, i.e., the department of plasma dynamics concerned with the production and control of intense beams of charged particles. The folloWing conditions are typically satisfied for the physical processes of plasma optics:

Static indetermination is a common problem in the dynamic analysis of most multibearing rotor systems. This paper presents a systematic treatment of this problem. It is taken into account at the stage when the general mathematical model is constructed for a complete multi-bearing rotor system. The p
