HEAT AND EFFICIENCY MASS TRANSFER IN PACKED LAYERS
The article focuses on the processes of turbulent transfer of heat and mass in one – and two-phase media in a stationary Packed and granular layers with chaotic and regular structure. Considered a one-dimensional model of heat and mass transfer in a turbulent boundary layer and theoretical expressions for the average transfer coefficients. Use of the properties of conservativeness of the laws of friction in the boundary layer in the presence of perturbations that allowed to apply the one-dimensional model for calculation of heat and mass transfer in Packed layers. The calculations are made, the coefficients of heat and mass transfer are compared with experimental data of various authors. The calculated efficiency of mass transfer in the gas phase at film mode and shows the agreement with the experiment. A mathematical model was developed and theoretical expressions are used when designing and modernization of industrial units in a petrochemical complex.
