functionPecletNumber
Returns Peclet number from Reynolds and Prandtl/Schmidt numbers
Extends from Modelica.Icons.Function (Icon for functions).
Information
Defined to be the ratio of the rate of advection of a physical quantity by the flow to the rate of diffusion of the same quantity driven by an appropriate gradient.
In the context of species or mass transfer, it is the product of the Reynolds number and the Schmidt number.
- Pe = Re*Sc
In the context of the thermal fluids, it is the ratio of advection to conduction heat transfer rates.
- Pe = Re*Pr
