I'm working on simulating a flow that drag particles in a duct.
I already have the flow simulation, but when I try to add particle tracing for fluid flow, the particles go straight and don’t follow the flow.
The data that I’m using is here:
-Material: Air (built in)
-Physics:
*Turbulent Flow K-ε:
-Inlet. 5 m/s
-Outlet. 0
* Particle tracing for fluid flow:
-Particle Properties.
-Particle Properties: 1100[kg/m^3]/]
-Particle Diameter: 1E-3[m]
-Drag Force. Use the data from previous study
-Inlet. Number of particles=10
-Outlet.
The Geometry of the cilinder is 0.22m diameter.
The problem comes with bigger particles. When I use a particle with a diameter lower than 1E-4; it simulates the particle being dragged by the flow. If I use something greater than that; they all go straight.
Do you know if I can simulate bigger particles? i.e. 5mm, 3mm etc.
