    Distribution of mass fractions in the free jet of hot gas mixture

  • Original language description

    The paper deals with the determination of radial distribution of mass fractions of individual species of hot gas mixture flowing out of plasma torch into air of atmospheric pressure. The designed computing method is based on the continuity equation and diffusion is taken into account. The method was tested using real measured data. The approximation of measured radial dependencies of temperature and velocity by Gaussian functions makes it possible to transform the two-dimensional problem into the one-dimensional. As a result, radial distributions of molar fractions of various species and an estimation of the coefficient of turbulence are obtained.

    Rozložení koncentrací ve volném proudu horké plynné směsi

  • Czech description

    Článek se zabývá určením radiálního rozložení koncentrace jednotlivých složek horké plynné směsi vytékající z plasmatronu do vzduchu o atmosférickém tlaku. Výpočetní metoda je založena na rovnici kontinuity (včetně difuzního členu) a byla ověřena na reálných naměřených datech. Naměřené radiální závislosti teploty a rychlosti byly aproximovány Gaussovými funkcemi.
