Lattice Boltzmann Method — Lesson 4

This lesson covers the mesoscopic lattice Boltzmann methodology, a crucial concept in understanding two-phase flow and heat transfer. It delves into the algorithm for solving multi-phase flow using this methodology and provides a practical demonstration using freeware. The lesson also explains how to install the software, set up model parameters, run a case study, and analyze the results. It further discusses the importance of collision and propagation in the lattice Boltzmann methodology. For instance, the lesson uses the example of colliding bubbles to illustrate the application of this methodology.
