Stanton number

One of the characteristic measures for thermal processes. It shows the intensity of energy dissipation in the flow of a liquid or gas: $$ \mathrm{St} = \frac{\alpha}{c_p \rho v} $$ where $\alpha$ is the coefficient of heat emission, $c_p$ is the specific thermal capacity of the medium at constant pressure, $\rho$ is the density, and $v$ is the velocity of the flow.

The Stanton number is related to the Nusselt number $\mathrm{Nu}$ and the Péclet number $\mathrm{Pe}$ by the relation $\mathrm{St} = \mathrm{Nu} / \mathrm{Pe}$.

The Stanton number is named after Th. Stanton.
