Free falling particle due to gravity in a linear density stratified fluid was investigated theoretically and experimentally. The equations governing particle motion in a homogeneous viscous fluid can be applied to this case if the density stratified fluid body is considered to be composed of infinite homogeneous layers of finite thickness. The particle motion is found to be a function of the fluid density gradient. The proposed calculation of particle displacement can describe the phenomena of particle sedimentation in zones of thermoclines in most natural water bodies. (Author)
