C l

Definition

relation between energy transfer associated with fluid momentum and energy transfer by thermal conduction in forced heating, expressed by

$C l = v^{3} l ρ / (λ Δ T)$ ; where

$v$ :: is speed (ISO 80000-3: Space and time),

$l$ :: is length (ISO 80000-3: Space and time) of the path of energy transfer,

$ρ$ :: is mass density (ISO 80000-4: Mechanics),

$λ$ :: is thermal conductivity (ISO 80000-5: Thermodynamics), and

$Δ T$ :: is difference of thermodynamic temperature $T$ (ISO 80000-5: Thermodynamics) along length $l$
