Abstract

Analizirano je numerično modeliranje stenskega uparjanja na primeru grelne cevi na sredini druge cevi. Opisani so uporabljeni modeli in enačbe. Za ustrezno uporabo modelov je izvedena simulacija validacijskega primera uparjanja v vertikalni cevi po eksperimentalnih podatkih Bartolomei-ja ter Lee-ja. Opravljena je simulacija praktične izvedbe, za katero so prikazani rezultati. Ovrednotena je praktična vrednost dobljenih rezultatov na manjših aplikacijah za pridobivanje nasičene pare pri atmosferskem tlaku.

Secondary title:	Numerical analysis of wall boiling
Secondary abstract:	The boiling process of wall boiling is analysed on a concentric tube-in-tube testcase. Used models and equations are presented. A validation testcase with practically obtained results is simulated for an externally heated vertical tube, as experimented by Bartolomei and Lee testcases. Results of a practical execution are simulated and presented. Obtained results are analysed for smaller applications of saturated steam producement at atmospheric pressures.
