Self-induced velocity correction for improved drag estimation in Euler–Lagrange point-particle simulations

S Balachandar, K Liu, M Lakhote - Journal of Computational Physics, 2019 - Elsevier
Abstract In Euler–Lagrange (EL) simulations the force on each particle is obtained from a
point-particle model, which is then coupled back to the fluid momentum. The feedback force …
