In this Master’s thesis, we have experimentally evaluated the deposition of liquid film on a moving surface at a liquid volume flux rate from 50 μl min^(-1) to 150 μl min^(-1), at moving surface velocities from 0.2 mm s^(-1) to 2.0 mm s^(-1) and for distances from moving surface from 0.3 mm to 0.9 mm. We have performed an analysis of the thickness, width and stability of liquid film in dependence on the aforementioned process parameters. We have designed and assembled the whole experimental setup. For experimental measurements, we have used deionised water. All measurements were captured with the optical method and analysed based on computer vision with Python software that was purposefully developed. The resulting liquid films had thicknesses and widths in range of 0.58 mm - 2.28 mm and 2.11 mm - 4.35 mm and have exhibited either stable operation or unstable swelling and weeping at the upstream meniscus. We found that the repeatability of liquid film deposition on a moving surface is worse for analysing liquid film thickness and stability, but better for analysing liquid film width. At all analysed process parameters there was visually apparent slip between liquid and moving surface that was randomly decreasing and increasing. We have concluded that water is in the examined range unsuitable for predictable liquid film deposition on the surface of polyimide tape.
