The instability in two-layer slot coating flows - ISCST
AbstractCoating is the process of applying thin liquid layers to a substrate, often a moving web. Complex coating processes can be approached through examination of their fluid mechanical components. The flow elements reviewed in this article include the boundary layer along a moving wall, the dynamic wetting line, withdrawal from a pool, flow metered by a narrow channel, die flow, flow on an incline, the freely falling liquid curtain, premetered coating with a small gap, and flow after coating. Coating Die Design for Suspensions - ISCST The die geometry based on the 1D lubrication approximation for different Bingham numbers are displayed in Fig.3, For a given coating fluid, geometric parameters and operational variables, the lubrication model can lead to an Computational flow analysis for coating die manifold design Computational flow analysis for coating die manifold design ... slot coating method, can produce such thin films with precise controlling the thickness in high speed. The coating liquid is pumped to the slot die that has a large cavity inside, which is called the die manifold. Conventionally, the role of the manifold is distributing the liquid to maintain a high degree of uniformity in the cross-flow direction. The distributed liquid flows into the feed slot and ejects onto a moving ...
