Taylor Number
Description
In fluid dynamics, the Taylor number (Ta) is a dimensionless quantity that characterizes the importance of centrifugal “forces” or so-called inertial forces due to rotation of a fluid about an axis, relative to viscous forces.
In 1923 Geoffrey Ingram Taylor introduced this quantity in his article on the stability of flow.
