We have investigated the behavior of non-circular particles interacting and colliding with internal circular obstacles in a fluid channel. The particle shapes, which are ellipse, pentagon, square, analyzed to examine effects motion interaction cylinders (obstacles). An Eulerian approach, employs fixed mesh background, is utilized. treatment within entire domain carried out using fictitious boundary method finite element method. used modified form repulsive force collision model treat between general shapes obstacles. particulate flow numerically computed multigrid solver FEATFLOW. Numerical experiments conducted by considering that different gaps them domain. drag coefficients on evaluated for very fine refinement level-6. A numerical comparison performed study impact shape settling Additionally, observe elliptical, pentagonal shaped particles. major goal investigate falling lift been compared existing literature
