As part of an attempt to develop a seawater RO desalination system utilizing the high static pressure of the deep-sea, a numerical analysis was performed to determine the axial variation of velocity, concentration and pressure in laminar natural convection flow, caused by the concentration difference in the moderately narrow annular passage formed between a tube type membrane and a cylindrical rod.<BR>A dimensionless equation was formulated from the numerical results to predict the transmitted fresh water flow rate from the width and the length of the passage, the submerged depth of the device, the permeability of membrane, and the physical properties of seawater. The transmitted fresh water flow rate exhibited an increase with decreasing width of passage up to a maximum at a width of about 1-2 mm, followed by a rapid decrease, and thus realized the existence of the optimum width of passage.
