Molecular Dynamics of Two-Phase Flow — Lesson 1

This lesson covers the fundamental aspects of molecular dynamics, focusing on two-phase flow and heat transfer. It delves into the understanding of multi-phase flow from a molecular perspective, discussing the nature of Vander Waals and columbic forces acting on molecules. The lesson also includes a case study based on molecular dynamics freeware, demonstrating how to install the freeware, set up model parameters, run the case study, and analyze the results. It further explains the scales of problems, different methodologies for continuum mechanics, and the molecular features of matter. For instance, it's like understanding how water molecules interact with each other and how these interactions influence the flow and heat transfer in a system.
