Résumé

The article reports on the results of experimental studies on the characteristics for a falling film absorber which is made up of 24 row horizontal smooth tubes. It shows that while the mass transfer coefficient is increased with the increase of spray density, the heat transfer coefficient is increased only in the small spray density range. There is an optimum spray density at which the heat transfer coefficeint is maximum. The heat transfer coefficient (Nusselt number), which is traditionally expressed using Reynolds number and Prandtl number, was modified taking the effect of inlet solution concentration into account. The results can be used to optimize the future design of absorption machines having a falling film absorber and using lithium bromide-water as working fluid.
