Information
The Peclet numver is 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, the Péclet number is the product of the Reynolds number and the Schmidt number.
- Pe = Re*Sc
In the context of the thermal fluids, the thermal Peclet number is equivalent to the product of the Reynolds number and the Prandtl number.
- Pe = Re*Pr
