Study of the stationary state of dissociating dimers in nonisothermal ideal gas phase

摘要

The binary ideal gas closed system of the dissociatingndash;recombining components dimer A2and monomer A is studied in nonisothermal stationary state. The stationary form of the internal energy transport equation for this system is divhyphen;gradGgr;=0, with Ggr; (T) =FTT0lgr;udTwhere the conductivity coefficient of internal energy flow lgr;uis a function of the variables: temperature, partial pressures in and heat conductivity of the mixture, enthalpy of dissociation, binary diffusion coefficient, and thermal diffusion ratio. A method for calculating the following variables and functions characterizing the steady state is given: equilibrium composition, net reaction rate, component mass fluxes, internal energy flux, reduced heat flow, and chemical contribution to energy transport.
