COMSOL Tutorial: Particle Tracing with Turbulent Flow

In this tutorial, I demonstrate how to use COMSOL Multiphysics to model fluid flow and particle tracing in a duct. You’ll learn key steps such as creating geometry, defining boundary conditions, setting up physics interfaces, and visualizing with streamline and particle trajectories. We’ll explore Turbulent Flow k-omega and Particle Tracing physics interfaces, using both Stationary and Time-Dependent studies to solve the problem.
I’ll show you how to:
Create the geometry using rectangles, partition objects, and delete operators.
Define particle properties like diameter, density, and initial velocity.
Add drag force and boundary conditions to simulate particle motion accurately.
Visualize results using particle trajectories, streamlines, and animations.
