Code exchAnge for Rubi Analysis Tools

CARAT is a consortium of international researchers, which was founded within the framework of the Multiscale Boiling Project (RUBI). Many of the participating research institutes have already developed computer-aided methods in order to efficiently evaluate the huge amount of experimental data. Within the framework of the CARAT project, these methods are to be bundled and jointly optimised.

In the framework of RUBI between 600 and 700 different parameter combinations will be investigated. Such an extensive project poses a special challenge for the data evaluation in order to achieve the best possible result and the greatest progress from the investigation. As part of the overall campaign, for example, around 15 million images will be generated and transmitted from the International Space Station to the scientists. Many of the participating research institutes have already developed computer-aided methods in order to evaluate such data efficiently and purposefully. Within the framework of the CARAT project, these methods are to be bundled and jointly optimised.

All participants have decided to make their developed methods available under the Creative Commons License CC-BY-SA.

RUBI is an experiment to investigate boiling phenomena which is carried out on the International Space Station (ISS) in 2019. This ESA-funded project offers European scientists and their associated colleagues a unique opportunity to gain a deeper understanding of the physical processes of boiling. The results of this project will not only be used for heat transport in weightlessness. Rather, the deeper understanding of boiling processes will allow a better prediction and design of heat transfer processes on Earth. These processes play a relevant role in a multitude of technical applications like power plant, refrigeration units, and chemical industry. But even every refrigerator at home or the air conditioning in the car use similar processes.

CARAT focus

  • automated evaluation and reconstruction of the bubble geometry
  • the automated calculation of heat flows based on thermographic temperature data
  • the automated acquisition of variables such as bubble frequency, position etc.
  • efficient data management
