Laminar radial flow electrochemical reactors. I. Flow fields

摘要: The velocity fields of three laminar radial flow electrochemical reactors are modeled using numerical and semi-analytical techniques. capillary gap cell configuration is Galerkin finite element (GFEM) analysis the asymptotic form its velocities presented. An approximate expression for entry length also derived compared to predicted lengths from GFEM. Qualitative agreement achieved. Two areas separation observed, their location being a function width, Reynolds number (Re) inlet pipe diameter. rotating electrolyzer (REL) field simulated with GFEM model. insensitivity REL profiles as rate shown. shape degree jets shown be determined by Taylor (being ratio half-gap width over theoretical boundary layer thickness). solution provide better estimate this than cell. Unlike previous cells pump shows less behavior therefore more difficult simulate. approach usually too costly perturbation techniques applied. resulting adequately represents broad range parameter values very short easy implement. One high simulation performed previously reported decoupling electrodic mass transfer interpreted via profiles.
