[1E07] Study on the DNB heat flux improvement by mixing vanes

*Keito Kamei1, Shinichi Morooka1 (1. Waseda Univ.)

Keywords:CHF, DNB, mixing vane, CFD, PWR, Spacer

This study's aim is to predict DNB in vertical tube by numerical analysis and increase it by mixing vanes. Calculating the temperature distribution inside the tube using CFD and incorporating it into the prediction model makes it possible to predict DNB.
