Researchers and students often struggle to understand how molecular diffusion is influenced by interparticle distance and partitioning coefficient, two key factors that explain how substances mix at the microscopic level. Molecular diffusion refers to the movement of particles from regions of high concentration to low concentration, interparticle distance describes how far apart those particles are, and the partition coefficient reflects a substance’s preference to distribute between two different phases at equilibrium. These concepts can be highly abstract, making it difficult to understand and relate them to how materials behave in real systems.
Our tool turns this complexity into an intuitive, interactive simulation that encourages exploration and deeper understanding for a broader audiendce.
This project is motivated by molecular simulation research in the Chemical Engineering Department, where transport phenomena play a central role. A fundamental skill for chemical engineers is the ability to predict and control how materials interact and diffuse. This key concepts have a wide range of applications in energy, materials, and biotechnology.
Our visualization illustrates concentration field simulation data from both two-body and many-body systems. Users can interactively adjust key parameters; interparticle distance (d) and partition coefficient (K); to observe how they influence the rate of exchange between materials. Material A is represented in red and Material B in blue, with color intensity indicating concentration levels. Animated visualizations show how these concentrations evolve over time, complemented by quantitative indicators that help interpret the exchange dynamics.
