The initial acceleration of a buoyant spherical bubble revisited
Dieter Bothe, Jun Liu, Pierre-Etienne Druet +3
An analytical derivation of the buoyancy-induced initial acceleration of a spherical gas bubble in a host liquid is presented. The theory makes no assumptions further than applying…

Compressibility and volume variations due to composition in multicomponent fluids
Pierre-Etienne Druet
For single components fluids, vanishing isothermal compressibility implies that the mass density is constant, but the same conclusion is unknown for multicomponent fluids. Here the…
