Prediction of subcooled flow boiling characteristics using two-fluid Eulerian CFD model

TL;DR: In this article, a detailed analysis of flow boiling phenomena under high pressure systems using a two-fluid Eulerian approach provided by a Computational Fluid Dynamics (CFD) solver is presented.
Journal ArticleDOI

Assessment of RELAP5 matrix solvers for a two-phase natural circulation loop

TL;DR: In this paper, three different approaches of linear-equation solvers for the hydrodynamic model are presented: the sparse matrix solver based on the Lower-Upper (LU) decomposition, the Border-Profile Lower Upper (BPLU) solver and the iterative method named Generalized Minimal Residual Method (GMRES).
Journal ArticleDOI

A problem in the COBRA-EN code related to the void fraction calculation

TL;DR: In this article, two solutions are proposed to solve the problem when a certain void fraction value is reached in the two-phase flow regime, a problem occurs in the COBRA-EN code.
Journal ArticleDOI

Application of the PN method to the matrix form transport equation

TL;DR: In this paper, the authors calculated the neutron group fluxes through the implementation of the matrix form transport equation solution by the P N method and the main objective is to obtain accurate numerical results.
Journal ArticleDOI

Computer codes for spectrum average cross section calculations

TL;DR: Considering the criteria of cost, availability, versatility and completeness the PREPRO2000 codes are considered the best option for researchers in developing countries involved with spectrum averaged cross section calculations.
