An empirical methodology for the design of vertical-tube absorbers.

Author(s) : PATNAIK V., MILLER W. A., PEREZ BLANCO H.

Summary

An analytical model was developed for the water-lithium bromide vertical-tube absorber by Patnaik et al. (1993). Model output was compared to experimental data from two different sources for the smooth tube: Jianpin et al. (1985) and Miller et al. (1992). The data gathered by the latter also include advanced absorber surfaces: pin-finned (three), grooved, fluted, and twisted tubes. The performances of all seven advanced tubes were predicted adequately (within more or less 20% overall) within the experimental ranges covered by Miller's tests. Finally, the model was used to generate design charts for each type of absorber tube. Examples of the charts are presented with guidelines for their use in the design of prototypes.
