Deborah Number
The Deborah number is a dimensionless number often used in rheology that characterizes the fluidity of materials under specific flow conditions. It is based on the premise that given enough time, even a solid-like material will flow.
The Deborah number equals the ratio between the relaxation timescale (or molecular timescale) and the observation timescale.
