摘要：
A numerical analysis simulating the thermal striping phenomena in a 1/5 scale water model of Prototype Fast Breeder Reactor (PFBR) primary circuit is carried out. Two non-isothermal water jets are impinged on a lattice plate placed above the jets. Reynolds stress turbulence model is used to evaluate the temperature fluctuations near the plate. The jets with unity velocity ratio showed maximum temperature fluctuations. The cold jet dominated and hot jet dominated flows result in very high and low temperature fluctuations respectively. This paper presents the computational techniques adopted to simulate the non-isothermal jet mixing phenomena, the results obtained thereby and discussion of these results.
