Bac d'immersion
Laissez tomber sphères, cubes, gouttes… dans l'eau, le mercure, le miel — flottabilité et traînée.
About this tool
Liquid Immersion Tank drops a solid into a fluid under gravity, buoyancy (Archimedes), and a blend of linear + quadratic drag. Educational toy — not a CFD solver.
- Choose fluid density/viscosity (water, mercury, honey, …)
- Choose shape (sphere, cube, teardrop, plate, cylinder) and material
- Press Run to drop; stats show Re, Fb, Fd, immersed fraction
Teardrop uses a low Cd (~0.05–0.1) to illustrate streamlining. Honey’s high μ makes Stokes drag dominate.
