The Stanton number is a dimensionless number which measures the ratio of heat transferred into a fluid to the thermal capacity of fluid. It is used to characterize heat transfer in forced convection flows.
- <math>\mathit{St} = \frac{h}{c_p\cdot\rho\cdot V}</math>
where
- h = convection heat transfer coefficient
- <math>\rho</math> = density of the fluid
- cp = specific heat of the fluid
- V = velocity of the fluid
It can also be represented in terms of the fluid's Nusselt, Reynolds, and Prandtl numbers:
- <math>\mathit{St} = \frac{\mathit{Nu}}{\mathit{Re}\cdot\mathit{Pr}}</math>
where
- Nu is the Nusselt number
- Re is the Reynolds number
- Pr is the Prandtl number
