Key Points

Develop an accurate and robust lattice-Boltzmann computational method to analyze solid particle suspensions in inertial fluids across arbitrary solid-to-fluid density ratios.
Formulated a discrete Boltzmann numerical technique with specialized boundary condition implementations for impermeable solid particles in fluid flow.
Validated the numerical framework using two-dimensional flow over cylinders, shear flows, and two- and three-dimensional channel sedimentation benchmarks.
Computed dynamic trajectories for non-spherical bodies, including ellipses, ellipsoids, and prolate spheroids, under shear and sedimentation conditions with near-unity density ratios.
Demonstrated numerical stability and predictive accuracy across diverse benchmark cases without restrictions on the solid-to-fluid density ratio.
Provided novel dynamic simulation data describing the rotational and translational motion of elliptical and spheroidal particles undergoing shear flow and sedimentation.
