摘要: Mixing characteristics of supercritical injection studies were analyzed with regard to the necessity include diffusive fluxes. Therefore, speed sound data from mixing jets investigated using an adiabatic model and compared analytic solution. In this work, we show that generalized application may become inappropriate for subsonic submerged at high-pressure conditions. Two cases are discussed where thermal concentration driven fluxes seen have significant influence. To which extent is valid depends on relative importance local fluxes, namely Fourier, Fick Dufour diffusion. This inter alia influenced by different time length scales. The experimental a n-hexane/nitrogen jet numerically. Finally, based recent numerical findings, plausibility thermodynamic models binary mixtures under high pressure conditions analyzed.
