Which physics is better to model the dispersed particles in the continuous phase?
Diffusion of particles or the Euler-Euler model, laminar flow?
Please give me your opinions on their pros and cons and what purpose do they serve in modelling the dispersed particles in the device? What type of different information will give you by each physics?
I really appreciate your answer.
I am not an expert in computational analysis of microfluidics. My info will be restricted on experiences in CFD modeling of fluidized beds. I guess your velocities will be low and turbulence modeling is not very compulsory. Since your geometry will not be very large, I guess your mesh number is not very large. I would recommend you to approach with Eulerian-Lagrangian modeling (rather than Eulerian-Eulerian) if you have strong computational power since they can cover the actual physics of the particulate flow better.
