Analysis Of Passive Heat Removal Systém Trough Steam Generator By Ansoft Fluent
Petrosyan, Taron
This paper presents the simulation of the condensation of water vapor in one tube of the heat exchanger in the Passive Heat Removal System, which is a protective safety system of the Nuclear Power Plant. The simulation accounts for the turbulent flow of the gas along the tube with an assumption of constant wall temperature. The results from the CFD (computational fluid dynamics) simulations are compared with the experimental results from the literature for the condensation of water vapor and in general, agree well.
Analysis Of Passive Heat Removal System Through Steam Generator
Petrosyan, Taron
In the current study, the model of Passive Heat Removal System (PHRS) through Steam Generator (SG) was developed for computational fluid dynamics (CFD) analysis. During work there was done three main tasks, which are creating geometrical form of PHRS, meshing of model to achieve a better analysis of thermal-hydraulic phenomena and creating domains for simulation steam condensation in PHRS SG heat exchanger tubes. Analysis through the "ANSYS CFX" software, with two different cases investigated at the steam inlet velocity of 1 m/s and 3 m/s. A thorough description of the steam condensation process in the passive cooling system obtained as a result of the analysis. The rate of the steam condensation in heat exchanger pipeline was assessed.
