Simulated foam formation now possible for the first time

A new clever algorithm makes it possible for the first time to carry out simulations with thousands of foam bubbles. These simulations are relevant for a range of industrial activities. Researchers from the Swiss Federal Institute of Technology in Zurich (ETH) have now successfully realized this further development to what is known as the volume of fluid (VOF) method. The research group’s work has even been presented in the scientific journal “Science Advances”.

The new Multi-VOF method allows the researchers “to perform simulations with industrial relevance using thousands of bubbles” for the first time, explains study leader Petros Koumousakos, Professor of Computational Science at ETH Zurich and Harvard University, in a report jointly published by the Swiss National Supercomputing Centre (CSCS) and ETH Zurich. The Piz Daint supercomputer used for the calculations is based at the CSCS. The CSCS has also uploaded a video to explain how these research findings are relevant for the production of foamed plastics, medical devices, food and cosmetics.

The new algorithm is said to be applicable to everything from tiny microfluidic devices to roaring waterfalls. According to the information in the report, the algorithm records complex processes without additional effort and is easy to implement in existing software. Its efficiency enables extensive studies focused on the control and optimization of bubbling flows. In addition, the new process is compatible with existing methods, the press release explains.
