【 摘 要 】

References(7)Cited-By(2)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 (c – us)/us0, which is defined by the ratio of the difference between wave velocity c and time-average surface velocity us to the amplitude of surface velocity fluctuation us0 in the streamwise direction, and the surface velocity ratio us/us0. The solution shows that the effect of progressive wave motion relative to the moving liquid surface on gas absorption is very significant.
