GROWTH OF A LIQUID-FILM ACCOMPANIED BY A ZERO-ORDER REACTION

The growth of a thin liquid film surrounded by gas pocket(s), undergoi ng absorption with a zero-order chemical reaction, has been simulated by an apt mathematical model in order to study the influence of variou s parameters involved. The solution has been obtained semianalytically using Goodman's integral method and solving the resulting differentia l equation by a fourth-order Runge-Kutta numerical integration algorit hm. The computations reveal the strong dependence of film growth on re action rate, diffusivity, and molar volume whereas the effect of gas-p ocket volume and initial film thickness are moderate.
