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)

Utilizzo

1. Cliccare su o scgliere Modello → Vincoli termici → Vincolo Scambio termico dal menu principale.
2. Selezionare nella vista 3D la superficie a cui il vincolo deve essere applicato.
3. Inserire la temperatura della superficie desiderata, il coefficiente del materiale e la temperatura ambiente.

Option

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).

Note

1. 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
