The Blake number in fluid mechanics is a nondimensional number showing the ratio of inertial force to viscous force. It is used in momentum transfer in general and in particular for flow of a fluid through beds of solids. It is a generalisation of the Reynolds number for flow through porous media.
Expressed mathematically the Blake number B is:
where
ε = void fraction μ = dynamic viscosity ρ = fluid density Dh = hydraulic diameter u = flow velocity
