摘要

Macroflows are considered for simulation of hot gas flow in a channel with nanopores. The flows are caused by the effects of gas slip, jumps of temperature and concentrations of gas mixture components on the surface of pores. The macroflows are obtained by averaging microflows in nanopores. The intensities of slip processes and jumps of temperature and concentrations are presented in dimensionless variables as functions of porosity, coefficients of gas molecules reflection from the surface of pores, and coefficients of thermal and concentration accommodation. Heat and mass transfer is calculated at various intensities of slip processes and jumps of temperature and concentrations. The model developed is applied to synthesis of magnesium-zinc and nickel-zinc ferrite nanoparticles. The results are compared with the experimental data. The model uses the experimentally determined activation energy and ignition temperature, the slip parameters and jumps of temperature and concentrations of gas phase components on the surface of pores at high Knudsen numbers. The results of calculation agree satisfactorily with the measured values of temperature. The theoretical model allows predicting the characteristics of the combustion wave at both large and small porosity of the sample in the case of surface combustion.
