Abstract:Zaradi zapletenih geometrij in omejitev s površino, ki je na voljo za prenos toplote v raznih hladilnih sistemih, so računalniške simulacije ključnega pomena za njihov razvoj. V programskem paketu AVL FIRE se razvija modul, ki omogoča simulacijo prenosa toplote med trdnino in tekočino in vključuje pojav vrenja. Modul temelji na enofaznem modeliranju uparjalnega toplotnega toka po modelu BDL. Opisani sta simulaciji z dvema različnima programoma (Abaqus in AVL FIRE), na enaki geometriji, z enakimi robnimi pogoji. Iz primerjave je razvidno, da kljub enakemu modelu vrenja, ki ga uporabljata, programa dajeta različne rezultate.

Title:Numerical simulation of boiling heat transfer in a narrow pipe
Abstract:Due to complex geometries and limited contact surfaces which are available for heat transfer in various cooling systems, computational fluid dynamic (CFD) is very important for their development. Company AVL is adding to their commercial program package AVL FIRE a module which allows you to simulate heat transfer between solid and fluid domain including boiling phenomena. The module is based on single-phase boiling using BDL model. In Diploma two such a simulations are presented, one made in FIRE and one made with coupling two programs FIRE and Abaqus. Both simulations are based on the same geometry, boiling model and the same boundary conditions. From the results of simulations, a significant difference in computed temperatures can be seen.
Keywords:Heat transfer, computer simulation, boiling, BDL
