Eckert number - Alchetron, The Free Social Encyclopedia

The Eckert number (Ec) is a dimensionless number used in continuum mechanics. It expresses the relationship between a flow's kinetic energy and the boundary layer enthalpy difference, and is used to characterize heat dissipation. It is named after Ernst R. G. Eckert.

It is defined as

E c = u 2 c p Δ T = Advective Transport Heat Dissipation Potential

where

u is the local flow velocity of the continuum,

c_p is the constant-pressure local specific heat of the continuum,

Δ T is the difference between wall temperature and local temperature.
