dc.description.abstractThe deposition of corrosion products (particles) in cooling circuits of water-cooled nuclear reactors has been investigated using large eddy simulation and Lagrangian method (Reynolds number 2.5 x 10(5)). A particle equation of motion including Stokes drag, lift, buoyancy and gravitational forces is used for particle trajectory analysis. The fluid-particle effect is considered and the particle-particle interact is ignored in this work. Results obtained from the fluid field calculation showed good agreement with experimental data and the predictions of direct numerical simulations. The particle size, drag force, shear-induced lift force and gravity all affected the particle deposition process. The small sized particles tended to deposite near the duct center while large sized particles tended to deposite near the duct edge, which become more obvious with increasing particle size. Close to the bottom of the duct, the particle number density increased with particle size increasing, and a high concentration of large particles appeared in the region with flow velocities lower than the mean, while small particles distribute evenly throughout the flow.zh_CN
