Eötvös number

In fluid dynamics the Eötvös number (Eo), also called the Bond number (Bo), is a dimensionless number measuring the importance of surface tension forces compared to body forces and is used (together with Morton number) to characterize the shape of bubbles or drops moving in a surrounding fluid. The two names commemorate the Hungarian physicist Loránd Eötvös (1848–1919)and the English physicist Wilfrid Noel Bond (1897–1937),respectively. The term Eötvös number is more frequently used in Europe, while Bond number is commonly used in other parts of the world.
