Mineral Scale Buildup in Water Pipes

Описание: In this animation, I simulated mineral scale buildup inside a water pipe using a diffusion-limited aggregation model. This visualization shows both the dissolved minerals attaching to the walls of the pipe, as well as the efficiency of the pipe over time. We see different clogging behaviors (at the start vs. in the middle), and the effect of water hardness and flow speed on the hard water deposit rate.

This animation was created for the EPS 109 course "Computer simulations with Jupyter notebooks" at the University of California, Berkeley: https://militzer.berkeley.edu/EPS109. It offers a general introduction to computer simulations for all science majors. Participants will use the Jupyter notebooks to perform calculations, design 3D graphics, and build on existing computer programs. No prior programming experience is required. The course teaches fundamental skills for scientists and helps students with future homework. It covers data processing techniques as well standard simulations methods including Monte Carlo and molecular dynamics. The algorithms are illustrated with a variety of applications in earth and planetary science as well as astronomy.
