Slot coating fluid mechanics and die design

Abstract. We analyze the effects of inlet periodic pulsatile flows on the flow inside a slot-die manifold for different locations of the inlet feed port. Slot Coating - an overview | ScienceDirect Topics The coating quality and the coating weight uniformity in the slot die are a function of die design and die geometry. Recent advances in understanding the fluid mechanics in the slot die have resulted in computer programs that help us design the die internals and lips to meet the specified requirements. Since the coating fluid rheology is either known or can be measured, the die can be designed to give uniform flow across the width with no adjustments. Because the viscosity is relatively low ...

AbstractThis paper describes the fluid mechanics of the slot-coating process in the context of rapid layered manufacturing. It has been conjectured that slot-coating would successfully address a number of common difficulties encountered in the formation of thin layers from a highly viscous fibre—photopolymer composite liquid. The objective of the present study was therefore the development ...

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 ... The fluid mechanics of slide coating - cambridge.org Liquid is metered through one or more slots onto the inclined surface of the coating die, flows down that face and across a gap onto a fast-moving smooth surface. In this paper the steady, two-dimensional slide coating flow of a Newtonian liquid is analysed by solving the full Navier–Stokes system with the Galerkin/finite-element technique, spine parametrization of free surfaces and full Newton iteration. The lower meniscus in the gap is assumed to remain pinned at the die edge and the ... US Patent for Slot curtain coating apparatus and slot curtain coating ...
