NUMERICAL MASS TRANSFER STUDIES IN CASE OF CONVECTIVE FLOWS OCCURRENCE IN ISOTHERMAL TERNARY GAS MIXTURES
Краткое описание
Isothermal diffusion mixing in multicomponent gas mixtures at various pressures is studied numerically in He + Ar – N2 and CH4 + Ar – N2. It is shown that in systems where the diffusion coefficients differ significantly from each other, nonlinear distributions of the concentrations of the components arise with increasing pressure, which leads to a nonmonotonous density distribution of the gas mixture in the computational domain. The resulting nonlinearity is the cause of the formation of convective structured flows. The transition from the diffusion to the convective regime is characterized by a significant increase in the average mixing rate. The dynamics of the development of convective currents and their structure is investigated.
