Description	Článek prezentuje výpočet termofyzikálních vlastností směsi vodní pára – argon, která se používá k dalšímu zlepšování charakteristik plazmových hořáků stabilizovaných vodním vírem. Výpočty byly provedeny pro teploty od 400 do 50000K a 0.1 MPa. Nejprve byly klasickými metodami stanoveny složení a termodynamické vlastnosti. Poté bylyprovedeny výpočty viskozity, elektrické vodivosti a tepelné vodivosti ve 4. přiblížení Chapmanovy – Enskogovy metody. Je popsán výpočet srážkových integrálů se zvláštním zřetelem na interakce nabitých částic se stíněným Coulombovým potenciálem, kde je nutno pokrýt potřeby 4. přiblížení. Jsou stručně představeny vztahy, popisující metodu řešení soustavy Boltzmannových integrodiferenciálních rovnic, založenou na variačním principu a jsou uvedeny hodnoty transportních koeficientů. (cs) The paper presents the calculation of thermophysical properties of the mixture water steam – argon which has been used to further enhance the characteristics of plasma torches stabilized by the water wortex. The calculations were performed at the temperatures 400 to 50000K and at 0.1MPa. First, the composition and thermodynamic properties are determined by classical methods. Further the calculations of viscosity, electrical conductivity and thermal conductivity of the mixture are computed in the 4th approximation of the Chapman – Enskog method. The computation of collision integrals is described with special respect to the interactions of charged particles where the necessary calculations for the Coulomb potential screened at the Debye length were enlarged to cover the 4th approximation.
