Physics of Low Flow Limit in Slot Coating - MAFIADOC.COM The region of feasible operation of a slot coater---a pre-metered coating device---is limited by several modes of failure. One of these modes, called the “low flow limit,'' occurs when the layer being deposited is so thin that the downstream meniscus recedes so far into the clearance between the downstream...

This type of flow rate disturbance can be caused by a coating liquid pumping mechanism that may lead to coating thickness nonuniformity. In this study, we analyze the transient behavior of the three-dimensional flows inside the slot-die manifold using parallel finite element computations.

The objective of the present study is to examine the validity of the theoretical predictions on the operating windows of slot die coating. The operating window is defined as a domain inside which stable and uniform coating is possible; different types of coating defects are found outside the window.
