Peclet Number

Péclet number, abbreviated as Pe, a dimensionless number, defined as a ratio of heat transport by convection to heat transport by conduction.

 

Peclet Number fromula

\(\large{ Pe =  \frac { v \; \rho \; C  \; l_c }{ k }      }\)

Where:

\(\large{ Pe  }\) = Peclet number

\(\large{ l_c }\) = characteristic length

\(\large{ \rho  }\)  (Greek symbol rho) = density

\(\large{ C }\) = heat capacity

\(\large{ k }\) = thermal conductivity

\(\large{ v  }\) = velocity
