WebThe electroosmotically induced flow field is studied by numerically solving the Stokes equations. The system attains a steady state under DC, where the conduction term of ion transport is balanced by the diffusion term. Until the system attains a steady state for a few ms for the case of DC, fluid flow is induced. WebSep 13, 2024 · Abstract. In this study, an analytical solution is proposed for the problem of transient anisotropic conductive heat transfer in composite cylindrical shells. The composite shells are considered to have directional heat transfer properties, which is due to the existence of fibers which can be winded in any direction. The composite shells usually …
