👉 Electrohydrodynamic (EDM) is a concept in fluid mechanics that describes the flow of electric charges through an interface between two conductive media. It involves the formation of electrochemical reactions, where the electrical charge density changes as a function of the conductivity and the direction of the flow. In the context of water, EDM can be applied to the transport of dissolved oxygen (O2) and carbon dioxide (CO2) in lakes or rivers. The flow of electrons through the lake bed creates
