This dataset was generated by Pauline Rothmann-Brumm (2023) as part of her dissertation at the Technical University of Darmstadt, Germany.

Title of the dissertation: Visualisierung, Analyse und Modellierung von fluiddynamischen Musterbildungsphänomenen im Zylinderspalt unter Anwendung von Maschinellem Lernen (German) / Visualization, analysis and modeling of fluid dynamic pattern formation phenomena in the cylinder gap using machine learning (English translation)

DATASET DESCRIPTION

URL: https://tudatalib.ulb.tu-darmstadt.de/handle/tudatalib/3961

This dataset contains MATLAB code for the creation of regime maps for gravure printed patterns from the HYPA-p dataset (see https://tudatalib.ulb.tu-darmstadt.de/handle/tudatalib/3841). The regime maps show the location of the three fluid splitting regimes, namely, point splitting, lamella splitting and transition regime, in a map of tonal value of the printing form over printing velocity.

The input for the code are the inference results of the trained convolutional neural networks (CNNs), as provided here (see https://tudatalib.ulb.tu-darmstadt.de/handle/tudatalib/3838). In this context, inference means automated classification of unlabeled data.

MATLAB CODE

Step by step guide:

1. Download folder 'code_RegimeMaps.zip' from https://tudatalib.ulb.tu-darmstadt.de/handle/tudatalib/3961. Unzip folder.

2. Optionally: Download the folder 'regime_maps.zip' from https://tudatalib.ulb.tu-darmstadt.de/handle/tudatalib/3961. Unzip the folder. It contains all the regime maps of fluid splitting from the dissertation of Pauline Rothmann-Brumm (2023). With the Matlab code, all these regime maps can be recreated.

3. Requirements:
- MATLAB R2022b
- matlab2tikz (http://www.mathworks.com/matlabcentral/fileexchange/22022 or https://github.com/matlab2tikz/matlab2tikz)
Download matlab2tikz and copy it to folder 'code_RegimeMaps'/2_Functions'.

4. Open 'plot_regime_maps.m'. 

5. Define variables 'exp_id' and 'ESA_variable' as desired (in the user input cell) and run 'plot_regime_maps.m'. 'exp_id' is the printing experiment ID and 'ESA_variable' defines if electrostatic printing assist (ESA) was used in the printing experiments. For more information about 'exp_id' and 'ESA_variable', please have a look into the code and into the dissertation of Pauline Rothmann-Brumm (2023).
