This is the data presented in the corresponding article in tabulated form

The results on five cases are given. two test cases include a horizontally oscillating cylinder in a rest flow and horizontal sloshing in a rectangular tank. Three water impact cases are a free falling wedge entering water, the water entry of a free falling multihull and the water entry of a free falling bow-flare ship section with various roll angles.

Video 1. Bubbles entrapment due to oblique droplet impact. ReL=220, VG=25 m/s. The video is slowed down 500 times. Video 2. Entrapment of bubbles due to oblique impact of remnants of a liquid bag onto the base film in front of a disturbance wave. ReL=360, VG=30 m/s. The video is slowed down 1000 times. Video 3. Entrapment of a large bubble due to overturning of a fast ripple wave. ReL=520, VG=25 m/s. The video is slowed down 1000 times.

Data: Code:Supplementary material: One video shows the underwater drone filming the bubble curtain. The second video shows an overview of the bubble curtain. The bubble curtain was 31 m wide and 10 m high with 2 mm holes drilled every 100mm. This research was carried out in the light of sound mitigation by bubble curtains. Both the hydrodynamic and acoustic properties of the bubble curtain were measured. The data was collected using an underwater drone with a camera and a stationary underwater camera.

These measurement data are obtained and analyzed as part of a research project on adiabatic gas-liquid flow in a cross-corrugated plate heat exchanger channel. (See list of publications below). The following Creative Commons license applies to the research data (images and measurement values) uploaded to the online repositories: CC-BY 4.0 Author: Susanne Buscher The measurement data is published in 2 data sets: Data set I: Original image data (4 parts): - uniform gas injection, part 1: https://doi.org/10.5281/zenodo.7985771; - uniform gas injection, part 2: https://doi.org/10.5281/zenodo.7986374; - uniform gas injection, part 3: https://doi.org/10.5281/zenodo.7986384; - non-uniform gas injection (part 4): https://doi.org/10.5281/zenodo.8067163 This data set contains the original photographs of the two-phase flow in the cross-corrugated channel obtained with a high-resolution camera. In addition, the corresponding experimental parameters and flow patterns (for part 1-3 only) are included in the CSV files. For uniform and non-uniform gas injection, respectively, the images were stored in sequentially numbered folders. The numbers of the folders correspond to the numbers of the measurement points listed in the attached CSV files with the associated experimental parameters. The image folders are grouped in ZIP archives. Each ZIP archive contains the single-phase reference images which can be used for the two-phase images to conduct background subtraction, because the lighting conditions are equal for all images in one ZIP archive. Data set II: Measurement values and processed image data: - https://doi.org/10.14279/depositonce-17868; This data set contains all measurement values and calculated results of all measurement points in the Excel and CSV files (e.g. pressure drop, volumetric flow rates, void fraction, measurement uncertainties). In addition, the results of the image processing algorithm are included in the Excel and CSV files (e.g. mean bubble diameter, maximum bubble diameter, local film flow ratio, extent of the two-phase distribution across the channel width, measurement uncertainties). The image folders contain the pre-processed images which were the input to the digital image analysis (i.e. the aligned and cropped image section of the channel without inlet, outlet, and peripheral regions and after subtraction of the image background), and the post-processed images visualizing the output of the digital image analysis for this image (i.e. detected objects are inserted as colored regions in the image section; the meaning of colors was explained in the publications of 2022 and 2023). In this dataset, the image folders are also subdivided into measurements with uniform and non-uniform gas injection and designated with the numbers of the measurement points, which are listed in the Excel and CSV files.
