Drag coefficient
The drag coefficient is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment.
D
Deborah number
Deborah number is the ratio of the time it takes for a material to adjust to applied stresses and the characteristic time scale of an experiment probing the response of the material.
D
Dean number
Dean number is the product of the Reynolds number through a pipe of diameter and the square root of the curvature ratio.
D
Damköhler number
Damköhler number is the relation of reaction timescale to the convection time scale, the volumetric flow rate through the reactor for continuous (plug flow or stirred tank) or semi-batch chemical processes. Damköhler number can be defined as:
