Literature survey on plasma instabilities(
Book
)
1 edition published in 1966 in English and held by 1 WorldCat member library worldwide
In order to prepare for planned work on plasma instabilities, a search was made of the literature. The report gives a survey on the material found. A short review is given of the various points of view under which the theoretical approach is possible. Interchange instabilities are then treated, which cover the largest field of phenomena, among them the so called 'negative V'systems and ballooning modes. The influence of finite resistivity and currentcarrier mass is next considered. A unified approach to resistive and microinstabilities completes the survey

MAGNETOHYDRODYNAMIC PROPULSION(
Book

The applicability of magnetogasdynamic concepts to the description of the flow in plasma accelerators is studied. Two methods are proposed for the theoretical treatment of steady crossedfield and travelling wave accelerators. (Author)

Numerical treatment of nonideal mgd basic equations(
Book
)
1 edition published in 1966 in English and held by 1 WorldCat member library worldwide
The mathematical treatment of the MGD basic equations is rendered extremely difficult by dissipation terms, as, e.g., caused by thermal conductivity, internal friction of finite electrical conductivity of the medium. Such terms give rise to a parabolic degeneration of the otherwise hyperbolic equations and, consequently, exclude the application of the method of characteristics which is usually used in the nondissipative case. Summarizing the treatment of a previous report, and generalizing some of its results, a numerical method of solution for the parabolically degenerated onedimensional MGD basic equations is given; it has been developed in analogy to the theory of characteristics. This method is advantageous insofar as it has  particularly for weak dissipation  similar stability properties as the method of characteristics (in the case of vanishing dissipation). Using this numerical method, the unsteady development of the structure of a magnetically driven shock under the influence of finite electrical conductivity is investigated in MGD(B<<1)approximation. The (B<<1)approximation was chosen since it leads to a particularly simple and perspicuous form of the basic equations

Gasdynamic methods in magnetohydrodynamics(
Book
)
1 edition published in 1966 in English and held by 1 WorldCat member library worldwide
In order to investigate the applicability and extension of gasdynamic methods for MHD flow, the generalisation of the Crocco theorem for plasmas and the conditions for potential flow in a plasma with infinite electrical conductivity were derived. Next twodimensional steady and onedimensional unsteady potential flows were investigated by the graphical characteristics and by variational methods. Then twodimensional steady and onedimensional unsteady problems for a plasma with finite electrical conductivity were solved and the new methods were applied to a travelling wave plasma accelerator, to crossedfield accelerators and to magnetic nozzles. It was shown that the new methods can be applied also to Hall propulsion devices to MHD generators and to viscid plasma flows with nonvanishing heat conductivity and with varying electric conductivity.

Magnetogasdynamic waves of small amplitude(
Book
)
1 edition published in 1964 in English and held by 1 WorldCat member library worldwide
The basic magnetogasdynamic equations are solved by two methods. In one the calculations are based on linearized equations, the propagation of plane waves being studied in a medium at rest. In the other the theory of characteristics is applied to more general perturbations. Both methods are shown to yield consistent results proving the existence of fast and slow magnetoacoustic waves

Mhd of a quasineutral plasma with vanishing internal friction and heat conductivity and finite electrical conductivity(
Book
)
1 edition published in 1965 in English and held by 1 WorldCat member library worldwide
The MHD basic equations for a quasineutral plasma are considered in the 1dimensional unsteady and 2dimensional steady cases. If the displacement current is neglected, the 1dimensional unsteady system is parabolic, and the 2dimensional steady system is elliptic. The influence of electrical conductivity on MHD solutions is investigated, and 3 methods for solving the general MHD equations are given. (Author)

Discontinuities in nonideal magnetogasdynamics(
Book
)
1 edition published in 1966 in English and held by 1 WorldCat member library worldwide
The well known evolutionary condition of ideal MGD is extended to nonideal, onedimensional MGD characterized by arbitrary dissipation terms. It is shown that in this case discontinuities may exist fulfilling the evolutionary condition. Concluding the case of a dissipation term due to finite electrical conductivity and its effect on contact discontinuities is investigated. These discontinuities are found to be nonevolutionary and therefore physically meaningless. (Author)
