Reverse osmosis membrane is the core component of seawater desalination system, and its performance is a key factor affecting the efficiency and quality of water production of seawater desalination system. In order to explore the working characteristics of the reverse osmosis membrane, the structure of the miniature unit of the reverse osmosis membrane is established, and its fluid domain is extracted, and the internal flow field distribution characteristics of the reverse osmosis membrane are analyzed by computational fluid dynamics simulation method. Through the numerical simulation, the variation law of the permeate quantity with the working pressure is obtained, and the distribution characteristics of the internal flow field of the reverse osmosis membrane are revealed. Besides, the main factors affecting the fluid flow efficiency and water yield in the reverse osmosis membrane are described.
