Heat and mass transfer in a turbulent nonequilibrium flow in an annular channel. Part 2. Thermal initial segment

Theoretical expressions are derived for the heat and mass transfer characteristics in a turbulent reacting flow in the initial themal section of a ring channel. The corresponding Sturm-Liouville problem has been solved numerically. Eigenvalues, eigenfuctions, and expansion coefficients have been tabulated. Quantitative criteria are derived for the asymptotic cases of quasifrozen and quasiequilibrium flow states, together with the expression for the length of the initial thermal section in a chemically non-equilibrium turbulent flow.
