In the International Fusion Materials Irradiation Facility (IFMIF), a lithium (Li) jet produced by a nozzle is designed as a deuteron-beam target to generate neutrons. To maintain integrity of the Li target, amplitude of surface waves on the jet is designed to be less than 1 mm. In this study, a numerical simulation with a CFD code was conducted to examine a boundary layer flow along the nozzle wall which directly affects generation of the surface waves. Calculation results with Large-Eddy Simulation (LES) model showed that Goertler vortices were generated along the wall near the nozzle exit. After flow separation at the nozzle exit, the generated Goertler vortices did not disappear underneath the free surface. This suggests the vortices affects generation of the surface waves near the nozzle exit.
