A numerical model is developed in order to understand the phenomenon, and to develop a capability of predicting the failure of reactor components caused by thermal stratification of the coolant. A period of this phenomenon in the surge line of a PWR reactor is simulated, in two-dimensions, using the TURBO computer program. The cylindrical geometry of ti.e flow is represented in 2D, by the space between two parallel plates, and the separation of these plates is estimated using similarity (the equivalence in the pressure drop). The results are compared with experimental data and with analogous results obtained from the COMMIX-1C code (3D).Para entendimento do fenômeno e desenvolvimento de capacidade de previsão de fainas em componentes nucle...
