Flow electrochemical batteries such as Al-Ago Batteries are high-capacity batteries that the electrolyte flows between the anode and cathode plates and the battery cell is in a close system. Due to the heaviness of such batteries, efforts are done to reduce their volume and weight so the distance between the anode and cathode is minimized. On the other hand, being to close to the anode and cathode increase the risk of short-circuit the battery. So, separators between the anode and cathode were used to prevent them from touch each other. Although preventing short-circuit, the separators are located in the direction of the electrolyte flow, preventing the desired flow between the anode and cathode plates. The flow wake due to their obstruction on the flow path affects the active area of the reaction and thereby reduces battery efficiency. On the other hand, the cross-section shape of these separators has a great influence on the hydrodynamics of the electrolyte, wake length and the active area of the reaction. In the present study, the electrolyte is considered as single-phase, steady and the effect of the number and arrangement of the separators are studied for four shapes of circle, square, Lozenge and triangle cross-sections on the electrolyte flow and the active area of the reaction
