Descriere
Această constrângere specifică schimbul de căldură (transferul de căldură al filmului) al unei suprafețe la temperatura T și cu un coeficient de schimb termic h și o temperatură ambiantă T0 . Fluxul de căldură convectiv q poate satisface: q = h(T -T0)
introduced in version 1.0: Can be also used to define a radiation heat flux on a surface.
Utilizare
Options
By default, this feature defines a convective heat flux. By using the option Surface heat flux, one can specify a heat flux value in Watts per surface area (W/m^2).
introduced in version 1.0: By using the option Surface Radiation, one can specify a radiation heat flux by setting a proper surface emissivity and ambient temperature.
