... fe = ρ e E′ + j × B where j = ρ e u is the electric current density. The second term in this relation is called the Lorentz force. When the fluid conductivity is very large as it is in the Earth’s core and in space plasmas, B depends on u and µ 0 j = ∇ × B, where µ 0 is the permeability of free spac ...

Euler`s equation
... The buoyancy force is equal the weight of the mass of fluid displaced, M = ρ0 V , and points in the direction opposite to gravity. If the fluid is only partially submerged, then we need to split it into parts above and below the water surface, and apply Archimedes’ theorem to the lower section only. ...

Fluid thread breakup
Fluid thread breakup is the process by which a single mass of fluid breaks into several smaller fluid masses. The process is characterized by the elongation of the fluid mass forming thin, thread-like regions between larger nodules of fluid. The thread-like regions continue to thin until they break, forming individual droplets of fluid.Thread breakup occurs where two fluids or a fluid in a vacuum form a free surface with surface energy. If more surface area is present than the minimum required to contain the volume of fluid, the system has an excess of surface energy. A system not at the minimum energy state will attempt to rearrange so as to move toward the lower energy state, leading to the breakup of the fluid into smaller masses to minimize the system surface energy by reducing the surface area. The exact outcome of the thread breakup process is dependent on the surface tension, viscosity, density, and diameter of the thread undergoing breakup.
