I started making one https://tinyurl.com/yj8g3rzp but doing it with primitives (circles and boxes) is too painful.

We will probably add a geometry editor later.

Project author here. The gallery is part of scientific software Aphros https://github.com/cselab/aphros for flow simulations. Examples in the gallery demonstrate what physical problems can be solved. The same configuration can be used on larger computers (including supercomputers). Intended for potential users of the software and those willing to learn some fluid mechanics.

Here's a post by the other author of the project https://news.ycombinator.com/item?id=26492582

This simulation is called a "Foaming waterfall". The waterfall captures air bubbles that rise to the surface and create foam. Similar effects are observed in oceans covered with foam generated by breaking waves. Our paper [3] describes the algorithm and contains more applications of this software stack. An online widget [4] shows the algorithm in two dimensions.

The application itself is easy to parallelize. And the production version does run in parallel (https://github.com/cselab/aphros) but relies on OpenMP and MPI. My first attempt to get C++11 threads running through WASM was not successful. Apparently, this feature is also disabled by default in some browsers because of the Spectre vulnerability.

Yes, I don't see why not. The model would not need electric current, and the concentration of dissolved gas would be replaced with temperature.

Thank you!

Initially, the container is filled with water (shown with white) and a layer of gas above (green). The reaction generates dissolved gases (red) on the electrodes. As soon as the concentration of dissolved gas reaches a critical value, it is converted into bubbles (green) that rise and merge with the existing layer of gas.

May remind somebody of their school chemistry class. But this one includes more things: fluid flow, electric current, diffusion, and nucleation of bubbles. Reduced from a scientific code to run directly in your web browser.
