Abstract: Analytical performance correlations for rotary heat and mass exchangers with infinite transfer coefficients have been presented in part I. A finite-difference model for performance prediction of rotary dehumidifiers with finite transfer coefficients is used in combination with the ideal dehumidifier model to establish effectiveness correlations. Correlations for the humidity and enthalpy effectiveness for silica gel regenerators are given as functions of the dehumidifier number of transfer units (NTU). An Effectiveness-NTU model, incorporating the correlations for the effectiveness and ideal dehumidifier performance, allows rapid calculation of the dehumidifier performance. The correlations are valid for a wide range of operating conditions and account for the effect of unbalanced flow and high Lewis numbers.
