Correlations for Film Regeneration and Air Dehumidification for a Falling Desiccant Film With Air in Crossflow

The coupled heat and mass transfer between a falling triethylene glycol (TEG) desiccant film and air in crossflow have previously been presented and solved numerically for the cases of regeneration and dehumidification. Here, correlations for the effects of independent variables on the rate of regeneration in the regenerator and on the rate of dehumidification and sensible cooling in the absorber are developed by statistical analysis of the numerical results. The functional correlations developed should be useful in the design of regenerators and absorbers having falling liquid desiccant films and air in crossflow.
