Nettet13. okt. 2024 · ABSTRACT. In this work, we study the axisymmetric motion of a prototypical swimming organism, a spherical squirmer, in a linearly density-stratified fluid. We assume the inertia is negligible, the stratification is weak, and the swimmer is oriented either vertically upward or downward. The swimmer acts as a settling particle … Nettet1. nov. 2016 · For drops smaller than the vertical extent of the stratified region, a linearly stratified fluid is a more appropriate model than a sharp stratification. Thus, the density of background fluid can be described as ρ b = ρ 0 − γ z , where ρ 0 is the reference density of the fluid, z is the vertical position and γ the background density gradient.
