Abstracts:
The paper presents the results of numerical simulation of fluid flow and heat transfer in a single-phase fluid flow in the pebble bed as for the cylindrical geometry as well as for the design of the fuel assembly with microfuel. The simulation was performed in the application package Anes. The testing models of package was carried out. Data modeling was comparison with experimental data obtained in the MPEI and with the data of other authors. The testing was obtained sufficiently accurate simulation. Disadvantages of the structure of the fuel assembly with microfuel was identified. |
