摘要：

An integral solution is derived for the problem of passive removal rate of a typical fission product (iodine), from a gas-vapor mixture, by condensate liquid film adjacent to a containment wall. The analytical model consists of a coupled set of five conservation equations: momentum, energy and three matter conservation equations for each individual component of the gas mixture: air, steam and elemental iodine. The set is solved in conjunction with two balance equations for the mass and energy transport at the interface with the condensate layer. The model accounts for free convection due to temperature and concentration gradients, for mass and thermal diffusion and for variable properties in both the liquid and the gas-vapor regions.
