Presented are the results of SERI's analytical studies of the mist-lift process for open-cycle OTEC. Results of a multiple-drop-size model that considers collisions and coalescence of drops indicate that drop growth is rapid. Results from an improved model that includes breakup of drops as well as coalescence indicate that drops tend to grow rapidly to a mean diameter of about 0.5 mm and that collisions prevent the drops from growing much larger than a few millimetres. Parametric studies performed using a single-drop-size model have indicated that the mist-lift process will perform under a variety of conditions. Important considerations for the design of mist-lift tube have also been identified as a result of these studies. Results of a transient mist-lift model indicate that the mist-flow process is stable to perturbations in operating condtions, as long as the conditions remain within the steady-state operational envelope for the particular mist-lift tube under study.
