The effect of two-dimensional progressive waves on the surface of a flowing liquid upon gas absorption is investigated theoretically. The convective-diffusion equation for mass transfer is solved on the basis of a boundary layer approximation. An analytical solution for the dimensionless average mass transfer coefficient is obtained as a function of three dimensionless numbers; the dimensionless streamwise distance, the relative wave velocity ratio (<I>c</I> – <I>u</I><SUB>s</SUB>)/<I>u</I><SUB>s0</SUB>, which is defined by the ratio of the difference between wave velocity <I>c</I> and time-average surface velocity <I>u</I><SUB>s</SUB> to the amplitude of surface velocity fluctuation <I>u</I><SUB>s0</SUB> in the streamwise direction, and the surface velocity ratio <I>u</I><SUB>s</SUB>/<I>u</I><SUB>s0</SUB>. The solution shows that the effect of progressive wave motion relative to the moving liquid surface on gas absorption is very significant.
