Taylor number

[′tā·lər ‚nəm·bər]
(fluid mechanics)
A nondimensional number arising in problems of a rotating viscous fluid, written as T = (f 2 h 4)/ v 2, where f is the Coriolis parameter (or, for a cylindrical system, twice the rate of rotation of the system), h the depth of the fluid, and v the kinematic viscosity; the square root of the Taylor number is a rotating Reynolds number, and the fourth root is proportional to the ratio of the depth h to the depth of the Ekman layer.
