Definition

quotient of density of heat flow rate and the difference of the temperature at the surface and a reference temperature:

h = \frac{q}{(\begin{matrix} T_{s} - T_{r} \end{matrix})}

where $q$ is density of heat flow rate (density of heat flow rate), $T_{s}$ is the thermodynamic temperature (thermodynamic temperature) at the surface, and $T_{r}$ is a reference thermodynamic temperature characterizing the adjacent surroundings

quotient de la densité de flux thermique par la différence entre la température de surface et une température de référence:

h = \frac{q}{(\begin{matrix} T_{s} - T_{r} \end{matrix})}

où $q$ est la densité de flux thermique (density of heat flow rate), $T_{s}$ est la température thermodynamique (thermodynamic temperature) à la surface, et $T_{r}$ est une température thermodynamique de référence caractérisant l'environnement adjacent
