Large Eddy simulation
 

Hi all, I am a beginner for using CFD fluent. is there any step by step tutorial to carryout particle deposition in square bend using LES.

Start with simulating the continuous phase by itself with a RANS turbulence model, then add particles (either Eulerian or Lagrangian; depending on your case); validating your results at each stage and checking mesh independence. Lastly, attempt the LES model, but be aware of the limitations and computational resources required for LES, especially for higher Reynolds numbers (read up on how scale resolved simulations work in Fluent). You may find it most practical to stay with the RANS model (is there a reason you're asking about LES?).

Thanks, I just started learning this software for my research... the article which read is based on LES (for nanoparticle flow and deposition characteristics). I have to carry out and validate , only then i can proceed with my work...
