*** General Introduction ***
This dataset contains data collected during experiments at Delft University
of Technology as part of the European Union's Horizon 2020 project called REFLECT
Deliverables from this project can be retrieved here: https://www.reflect-h2020.eu/deliverables
The content of this dataset has also partly been published as: 
Boeije, C.S., Zitha, P.L.J. and Pluymakers, A.H.M., 
“High speed imaging of degassing kinetics of CO2-water mixtures”, 
Physics of Fluids 34, 123307 (2022), https://doi.org/10.1063/5.0124500

It is being made public to act as supplementary data for both the REFLECT deliverable
and the journal publication.

The data in this data set was collected in the Geoscience and Engineering Laboratory of the
Delft University of Technology - Faculty of Civil Engineering and Geosciences, between August 2020
and December 2022.
As part of the REFLECT project, this project has received funding from the European Union’s Horizon 2020 
research and innovation program under Grant Agreement No. 850626.

*** Objectives of study ***
The purpose of these experiments was to investigate degassing of CO2-water mixtures under conditions
relevant to the production of geothermal waters. Topics of interest are the conditions under which 
free gas bubbles start to form during depressurization of these mixtures.

*** Experimental approach ***
Experiments consist of depressurization of CO2-water mixtures inside a high pressure visual cell. 
A high-speed camera along with pressure measurements are used to monitor the depressurization process.
An image analysis routine is used on the obtained images, which allows for determining at which pressure 
free gas bubbles begin to form along with parameters such as the bubble size. 

***Description of the data in this data set***
The data included in this data set show parameters such as the number of bubbles in an image as a 
function of the pressure in the cell. This is done for various initial conditions of the mixture. 
The filenames of the various files refers to the figure numbers from the REFLECT deliverable document.
Files are given as both Excel and comma separated values (CSV) tabulated data. 
In addition, MATLAB data files (MAT files) are given along with an accompanying script (M files) that 
can be used to plot the data. 
Furthermore, an example video of showing the image analysis performed on one of the experiments is given.
