Abstract:By researching into the phenomena of heat and mass coupling transfer between ammonia and water, the relationship of the inter action and inter affection between heat and mass transfer in a process of non insulation absorption is theoretically explained. The numerical computation model of heat and mass coupling transfer in a vertical falling film absorber of ammonia water is set up and computed. A new designing calculation method for a vertical falling film absorber is put forward.
Keywords:heat transfer  mass transfer  numerical computation/falling film absorption
