Dean Number
Dean number is proportional to { (Re . centrifugal force) / (inertial force) } and is used in momentum transfer in general and flow in curved channels calculations in particular. It is normally defined in the following form
De = (D.V.rho/mu) |
Where: | ||
D | = | Diameter |
L | = | Length |
mu | = | Viscosity |
R | = | Radius of curvature of bend |
rho | = | Density |
V | = | Velocity |
