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.
Keywords:Uparjanje, numerično modeliranje, računalniška dinamika tekočin, večfazni tokovi, RPI model stenskega uparjanja

Title:Numerical analysis of wall boiling
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.
Keywords:wall boiling, numerical modeling, computational fluid dynamics, multiphase flow, RPI wall boiling
