Webb27 juli 2024 · Settling velocity is usually taken to be constant. However, experiments on fluid sediment mixtures indicated that a substantial reduction of the settling velocity of particles occur due to the increased suspension concentration (also called hindered settling velocity; Woo et al. 1988; Mazumder 1994; Baldock et al. 2004 ).

The primary force is an applied force, such as gravity, and a drag force that is due to the motion of the particle through the fluid. The applied force is usually not affected by the particle's velocity, whereas the drag force is a function of the particle velocity.
