Towards practical use, applying a large-scale multi-pore system is necessary and almost inevitable. Unfortunately, due to the presence of a significant ionic concentration polarization (ICP) at a high pore density, the power generated per pore is usually much less than that generated from a single pore. To alleviate this problem, we propose applying a cross flow parallel to the pore openings. This lowers the degree of ICP, thereby improving its osmotic power generation performance. Several ways of applying the cross flow are examined, and the results of numerical simulation reveal that applying it on the lower salt concentration side only can yield the best performance. In this case, the osmotic power generated increases with the increased cross flow velocity. In addition to assessing the performance under various conditions, the mechanisms associated with the system under consideration are discussed. ? 2021 Elsevier B.V. |
