Hey Mathieu,
How would I go about creating the arrays? There would be a flow density parameter of 998 kg/m3 and a dynamic viscosity parameter of 1e-3 mPa/s to be added.
I would like to use LPT over stream tracers/particle tracer/etc as I want to model particle separation within a microchannel. My system models Dean Drag forces important for separation of particles. This occurs where secondary flow can lift and drag particles based on their size and density. Changing the flow rate, particle size or density can affect where particles move within the microchannel perpendicular to flow. Other stream tracers will only model the dominant flow and ignore the secondary flow effects fundamental for modelling the Dean Drag forces for separation and give the same result regardless of particle size and density. Below are some images of second flow demonstrating Dean Drag forces and stream tracers which lose all secondary flow information.
If I have misunderstood and there is a better way to achieve this modelling, please let me know. I am aiming for something similar, if not the same as this implementation in Comsol.
Images are a 500x200 micrometre channel demonstrating Dean Drag forces, a 200x200 micrometre channel demonstrating Dean Drag forces and finally stream tracers without any particle specific parameters.
