Abstract

V diplomski nalogi so bile simulirane tokovne razmere v vstopnem plenumu in v začetnem delu cevnega snopa uparjalnika tlačnovodne jedrske elektrarne. Naloga je bila izvedena s pomočjo programa za računsko dinamiko tekočin ANSYS CFX. Za potrebe simulacije je bilo potrebno nekatere parametre določiti z empiričnimi korelacijami. Originalen doprinos naloge je, da je bil cevni snop modeliran kot porozen medij. Rezultati so pokazali, da so masni pretoki skozi različne sekcije cevnega snopa različni. Posledično je termična obremenitev cevi cevnega snopa neenakomerna.

Secondary title: Simulation of flow conditions in the inlet plenum of a nuclear power plant steam generator with a computational fluid dynamics code
Secondary abstract: In the diploma, the flow conditions in the inlet plenum and the initial part of the tube bundle in a pressurized water reactor steam generator were simulated. The task was carried out with ANSYS CFX computational fluid dynamics software. For the needs of the simulations, some parameters had to be determined from empirical correlations. The original contribution of the assignment is that the tube bundle was modeled as a porous medium. The results showed that mass flows through different sections of the tube bundle are different. Consequently, the thermal load of the tubing (tube bundle) is uneven.
