Musabekova L., Dausheyeva N., Zhumataev N., Jamankarayeva M., 2016, On Modelling the Convective Mass Transfer over Moving Films Interface for the Reaction-Diffusion Systems of the Second Order, Chemical Engineering Transactions, 52, 217-222.
The paper deals with the methods for approximately analytical and numerical solving the non-self-similar problems of film absorption, accompanied by the partly reversible reaction of a second order. The Peclet number in this case is taken as sufficiently high, and the diffusion boundary layer is very thin. The methods to obtain approximate analytical solutions of the stationary convective diffusion equation for the coupled problem of isothermal film chemisorption at high Peclet numbers have been worked out. The approximate analytical method for solving the following problems: physical absorption of poorly soluble gas and chemisorption with partly reversible reaction of the second order with specially allowance for the kinetics of surface reaction has been submitted. The known Crank-Nicholson method expanded by the iteration procedures has been modified applying to mentioned problems, and preliminary results of computer simulations have been discussed. The obtained results are likely to be of importance to mass transfer modeling and engineering practice in industrial processes and apparatuses design.
