What is Peclet number ? What is the significance of Peclet number ?

Peclet number is a dimensionless number, expressed as the ratio of the material flux produced by the advection to the dispersed substance flux used to determine the dominant pollutant transport mechanism.

How is Peclet number calculated ?

Peclet number is calculated by multiplying Prandtl number and Reynolds number.

What is Peclet number used for ?

Peclet number is a dimensionless number used in heat transfer calculations. It is used for liquid metals whose prandtl numbers are very small. It is the ratio of diffusion to thermal diffusion that occurs with forced convection.

The Peclet number (Pe) is a dimensionless numbers relevant in the study of transport phenomena in a continuum. It is named after the French physicist Jean Claude Eugène Péclet. It 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.
