In this study, a tubular membrane-based liquid desiccant air-conditioning system was numerically simulated to obtain mass transfer correlation. The design parameters for the membrane-based liquid desiccant system (Re numbers and aspect ratio, L / D ) were also optimized using the numerically obtained results. The mass transfer correlation was developed as a function of Reynolds numbers, Schmidt numbers and aspect ratio which indicates a ratio of the length to the diameter of the membrane tube. The effect of the aspect ratio and airflow velocity on the efficiency of the membrane-based liquid desiccant system was also investigated. COMSOL Multiphysics modules of this study were validated with the literature results. The maximum efficiency was obtained as 50% with an aspect ratio of 40 at low Re number of 50.
