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)
Heat sink with convective heat flux load on the surfaces exposed to air
Utilizare
- Click pe
sau selctați Model → Thermal Constraints → Constraint heatflux din meniul principal. - Selectați în vizualizarea 3D suprafața/elepe care constrângerea trebuie aplicată.
- Introduceți temperatura dorită a suprafeței, coeficientul filmului și temperatura ambiantă.
Notă
- Constrângerea utilizează *FILM card in CalculiX. constrângerea fluxului de căldură este explicat la http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node203.html
