Linearly stratified fluid
Nettet28. des. 2024 · In most cases, particles passing through the stratified interface will increase the resistance of the fluid to particle motion. 16 In the low Reynolds number range, the increased resistance to particles settling in linearly stratified fluids is due to the viscous entrainment of the fluid in the high-density layer and the formation of a … Nettet15. mar. 2024 · The linearly stratified water was considered a mixture of freshwater and saltwater, whose density ρ varies linearly with depth from 1000 to 1100 kg/m 3. The thickness of the stratified water and position of the towed sphere were kept the same as in the experiments (Meunier et al., 2024; Rottman et al., 2004). The diameter D is 2.52 …

NettetInternal waves generated by the turbulent wake of a sphere travelling horizontally through a linearly stratified fluid were studied using shadowgraph and particle-streak photography. The Reynolds and internal Froude number ranges considered were 2,000 ≤ Re ≤ 12,900 and 2.0 ≤ Fi ≤ 28.0, respectively. Two quite distinct flow regimes based on …
NettetThe flow of a linearly stratified fluid past a sphere is considered experimentally in the Froude number Fi, Reynolds number Re, ranges 0.005 ≤ Fi ≤ 20 and 5 ≤ Re ≤ 10000. Flow visualization techniques and density measurements are used to describe the rich range of characteristic flow phenomena observed. 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 …
