A CFD Method for Thermal-Hydraulic Calculation of Pebble Bed HTGRs
Volume 8: Computational Fluid Dynamics (CFD) and Applications, 2022Abstract The high temperature gas-cooled reactor (HTGR) is an advanced reactor type with safety characteristics of Generation IV nuclear energy systems. In the design process of an HTGR, thermal-hydraulic analysis is of great significance.

Improving Thermal-Hydraulic Calculation Modules of THERMIX Code Based on LU Decomposition
Volume 4: Thermal Hydraulics, 2013THERMIX is a software package for analyzing the thermal-hydraulic and safety behavior of pebble-bed high temperature gas-cooled reactor under both normal condition and accident conditions. The point-wise iterative solution method of THERMIX is time-consuming and difficult to be extended.

Calculation Method for Thermal-Hydraulic System Simulation
Journal of Heat Transfer, 2008This paper presents the fundamental approaches of modeling thermal-hydraulic component briefly. A set of lumped parameter mathematical models is developed, which are based on conservation of mass and energy. Subsequently, the connection rule for basic thermal-hydraulic components and the method to automatically generate the complete thermal-hydraulic ...

High-Fidelity Coupled Monte-Carlo/Thermal-Hydraulics Calculations
SNA + MC 2013 - Joint International Conference on Supercomputing in Nuclear Applications + Monte Carlo, 2014Monte Carlo methods have been used as reference reactor physics calculation tools worldwide. The advance in computer technology allows the calculation of detailed flux distributions in both space and energy. In most of the cases however, those calculations are done under the assumption of homogeneous material density and temperature distributions.
