A.
Reynolds number
The Reynolds number is a dimensionless quantity in fluid mechanics that characterizes the flow regime of a fluid, indicating whether it is laminar or turbulent based on the ratio of inertial to viscous forces.
-
B.
Knudsen number
The Knudsen number is a dimensionless quantity in fluid dynamics that compares a gas’s molecular mean free path to a characteristic physical length scale, indicating whether continuum or rarefied flow models are appropriate.
-
C.
Chandrasekhar number
The Chandrasekhar number is a dimensionless quantity in magnetohydrodynamics that measures the relative importance of magnetic forces compared to viscous forces in a conducting fluid.
-
D.
Froude number
The Froude number is a dimensionless quantity in fluid dynamics that compares inertial forces to gravitational forces, commonly used to characterize flow regimes in open channels and around ships.
