Περίληψη: Numerical studies of bevelled circular disk settling dynamics with various shapes and sizes have been investigated in a quiescent fluid. Direct numerical simulations, together with an immersed boundary method, have been used to develop understanding of the settling process for these disks. High resolution and accuracy were facilitated using the spectral element method, as applied using the Nek5000 solver. The size of the particles (based on diameter, 푑) was considered in the 1-2 mm range, which falls in the intermediate flow regime with a maximum particle Reynolds number, 푅푒p = 835. A sensitivity analysis was performed for the particle and fluid mesh resolution. Settling velocities, disk orientations, and the local particle Reynolds numbers were recorded over time. The disks demonstrate motions in all three dimensions after release from rest, with a reciprocation during translation, and rotations about their three orthogonal axes. The upper limit of the Galileo number, Ga, was 370, which represents the relative importance of either gravitational or viscous forces, based on size, shape, and density ratio. Disks with sharp and bevelled edges were simulated and their settling rates compared, with enhanced settling rates found for the latter. [ABSTRACT FROM AUTHOR]
