Abstract
The purposes of present work are to analyze turbulent convective heat transfer downstream of mixing vane in subchannel of nuclear reactor with three-dimensional Reynolds-averaged Navier-Stokes equations. SST model is selected as a turbulence closure by comparing the performances of two different turbulent closures. Three different shapes of mixing vane are tested. And, thermal-hydraulic performances of these vanes are discussed. The results show that twist of the vane improves the heat transfer performance far downstream of the vane.
