Abstract: We investigated the gravitational settling of a single semi-torus shaped particle immersed in a viscous, incompressible fluid in two dimensions. To study the problem, numerical simulations were done using Immersed boundary (IB) method. Parametric studies were conducted to investigate the effect of varying parameters namely, density of the particle (for a fixed fluid density), fluid’s dynamic viscosity and particle’s size on the settling velocity of the particle considered. We also considered the particles in different orientations to investigate its effect on the dynamics of the settling particle. The results obtained were physically justified. The convergence studies done validated IB method’s spatial accuracy of first order.
