An electrochemical cell consisting of a double horizontal Impinging Jet Cell (IJC) has been conceived\nand characterized. The purpose of this system is the simultaneous electrodeposition of a\ncomposite metal/particle coating on both surfaces of a metal sheet. The silica particles imprint in\nthe nickel matrix has allowed to distinguish four different flow areas onto the electrode namely\nthe stagnation area, the radial flow area characterized by a higher flow speed, the return flow area\nthat involves gravity effect, and the drainage area with a constant draining speed. Based on the limiting\ncurrent evolution as a function of the Reynolds number, three flow modes were extracted:\nthe Laminar Low Flow (LLF), the Laminar High Flow (LHF) and the Disturbance. The IJC investigated\nensures a laminar flow for a large range of flow rate from a nozzle-to-sample distance of 19\nmm and creates an laminar flow ovoid plan merged with the sample for the high flows.
