Peclet number
In
physics, the
Péclet number is a
dimensionless number relating the
forced convection of a system to its
heat conduction. It is equivalent to the product of the
Reynolds number with the
Prandtl number.
There are various definitions of the Péclet number. The most typical are as follows:
Pe = l * v / α
Pe = l * v * ρ * cp / λ
Pe = l2 * ρ * cp / λ / t
Pe = Re * Pr
