The most important influence on the plasma of underwater discharges has the processes in a zone of its contact with condensed medium. At the initial stage of electrical pulse discharges (EPD) small-scale irregularities of heat flow distribution were detected on a surface of channels [1, 2]. Development of such perturbations was accompanied by space modulation of an irradiation intensity, strain of a surface of channels, drop of conductance of plasma. These excitations are connected with the development of Rayleigh-Taylor instability. Thus in EPD it may be realized the two different regimes of discharges the first is characterized by developed perturbation and the second is the discharges without it. Because of that the nonideal plasma of EPD takes place in various dense states. Also, that picture is established in underwater arc discharges. In this paper it is studied the peculiarities of the transport properties of the nonideal plasma of underwater discharges in the pressure range from 1 bar up to 200 bar. 1. METHOD TO CALCULATE TRANSPORT PROPERTIES It is considered the calculation of transport coefficients (thermal conductivity, viscosity, electrical conductivity) in dense water plasma. The most important factors determined the properties are the following: gaseous and plasma non-idealities, multicomponent contents. To include the factors into consideration the combined calculation procedure is used on the base of the Grad’s method [6, 7] and Lee- More theory [8]. The non-ideality corrections to equation of state are made according to [9-11]. The obtained results are compared with the previous calculations based on the Lorentzian theory (LM) [5, 12]. Also, the calculation data are considered to be in reference with transport coefficients obtained by using the Chapman-Enskog method [13,14] and reference data [15]. The algorithm of calculation consists of three stages. At the first time it is needed to obtain the multicomponent plasma composition under certain pressure and temperature. This problem leads to the system of Saha equations with lowering of ionization energies supplemented by conservation of nuclei and electric charge. The calculations are carried out, and the following 16 species have been taken into account: e - , H2O, H2O + , H2, H2 + , OH, OH + , O2, O2 + , H, H + , O, O + . Cu,Cu + ,Cu 2+ . Having been obtained plasma composition, the thermodynamic and transport properties of plasma can be calculated in the , so-called, zero-density model (ZM) i.e. without consideration of the nonideality effects. At next stage the nonideality corrections are included to obtain the set corresponding to the dense model (DM). A number of the properties are very interested in the connection of intended use to simulate underwater discharges. Therefore it is focused attention upon such properties. 2. RESULTS AND THEIR DISCUSSIONS The results of calculations are shown in Figs.1-6. One can see that the properties of dense water plasma have a pronounced non-monotone character with sharp pikes in certain temperature and pressure ranges. The pikes are appeared due to the dissociation, ionization and from others effects. The metal impurities are appeared in the discharge plasma due to the various circumstances. The influence of the metal admixtures causes the very important changes of the plasma properties (see Figs. 3, 6). It is obvious that the presence of impurities cause the growth of conductivity and energy density in plasma. 250 ISSN 1562-6016.

The results have a similar character at normal pressure (see Figs. 1, 4). On the other hand at higher pressure the essential discrepancy takes place (see Figs. 2, 5). One can be deduced that the effects of nonideality have influence on the transport coefficients mainly in more dense conditions and the Lorentzian theory is suitable to calculate the transport properties of multicomponent plasma at relatively low temperature and normal pressure. Also, one can see that the calculations of some properties are in a good agreement with the data from [13-15] at normal pressure. The results may be distinguished due to the various initial data for calculation. Fig. 4. Thermal conductivity of water plasma ( p =1 bar).

The properties have a pronounced non-monotone character with sharp pikes in certain temperature ranges. The calculations are carried out on the base of the Grad’s method including the nonideality effects. At atmospheric pressure the results are in a good agreement with the previous calculations and data calculated on the base of Chapman-Enskog’ method. On the other hand it should be pointed that the nonideality effects are needed ISSN 1562-6016. ВАНТ. 2015. №1(95) 251 to take into consideration under calculation of properties of underwater discharge at high pressure. The obtained results confirm the conclusion of paper [12] that the Lorentzian theory is suitable to calculate the transport properties of multicomponent plasma at relatively low temperature and normal pressure. Also, it is considered the influence of copper admixtures on the transport properties of water plasma. REFERENCES 1. A.V Kononov, P.V. Porytskyy, P.D. Starchyk, et al.
