Abstract
In the present article operating characteristics of LPG (liquified petroleum gas) revaporizer are analysed. At the beginning description of electrical revaporizer as well as the problem definition are presented. 2D numerical model of revaporizer is introduced and main assumptions for that simplification are explained. Governing equations of fluid flow in the region of natural convection and porous region of computational domain are given. Boundary conditions are prescribed on the basis of heat transfer empirical correlations for single- and two-phase flow in helically coiled tubes and correlations for external flow around revaporizer shell. Finally, results of CFD analysis and main conclusions are presented. Computational results show that revaporizer operates within prescribed temperature range for selected combination of process parameters.
