Abstract

Numerical methods for solving conservation equations using the DINUS code are presented. The DINUS code has been developed for direct numerical simulation of thermal-hydraulic phenomena in fuel rod bundles. To examine the methods, two test problems have been studied: turbulent flows between parallel plates and in a Triangular-Arrayed rod bundle.
