Numerical analysis using CFD code for rectangular open channel experiments has been carried out to development an evaluation method for gas entrainment phenomena at free surface of a sodium-cooled fast reactor. From the point of validation of the evaluation method, Strouhal number of vortex frequency and velocity distributions obtained from the numerical analyses were compared with experimental results. As the results, the Strouhal number of the vortex frequency behind the plate obstacle and the velocity distributions reasonably agreed with experimental results.
