Descrizione
Questo vincolo specifica lo scambio termico (film heat transfer) di una superficie a temperatura T e con un coefficiente di scambio termico h e una temperatura ambiente T0 . Il flusso di calore convettivo q è in grado di soddisfare: q = h(T -T0)
introduced in version 1.0: Can be also used to define a radiation heat flux on a surface.
Utilizzo
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.
Note
- Il vincolo utilizza la *FILM card in CalculiX. Il vincolo scambio termico è spiegato in http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node203.html
