Abstract

Abstract

3-D single-phase flow field in rod bundles with spacer grids was studied using numerical methodology.Using hybrid grids technique,employing standard k-ε model and SIMPLEC algorithm,the axial velocities obvious near the spacer grids than lateral velocities,it also influence the resistance characteristic obvious.Mixing vane affects lateral velocities much,and blends the axial velocity.
