Time evolution of the drag force and its components for q = 0.25, C_d = 0.23, and C_h = 4.0. The visualization of these quantities represents how each of them enters the drag force according to Eq. (5). The drag force is in the nonlinear regime, i.e., ℳ > 1.01 and η_ℬ > 0.1, during the whole simulation. The ratio between the drag force and the gravitational force, F_g, is also shown. The vertical dashed gray line indicates the end of the dynamical plunge-in phase as determined by Eq. (22).
