Скачать или смотреть CFD-DEM Explained: The Science of Fluids & Particles | Science Explained

Ever wondered how engineers simulate millions of particles moving inside reactors, dryers, or gasifiers? Welcome to the fascinating world of CFD-DEM—Computational Fluid Dynamics combined with the Discrete Element Method.

In this lecture-style video, we break down how CFD-DEM bridges microscopic particle motion with large-scale industrial performance. You’ll discover why this method is so powerful, how it couples fluid dynamics with particle physics, and what makes it indispensable in chemical engineering, energy, and materials science.

We’ll start with the basics—what multiphase systems are and why they’re so difficult to model. Then, we’ll dive into how CFD-DEM actually works, exchanging forces between fluid and particles at every time step. Finally, you’ll see the real-world applications: from drying and coating processes to combustion, gasification, and clean energy technologies.

If you’re an engineer, scientist, or simply a curious learner, this is your chance to understand one of the most advanced modeling tools shaping the future of process design.
