Moving Rotational Vane for CHF enhancement by vortex generation

  • 3D-printed rotational mixing vane adoption in subchannel
  • Modeling and validation of flow-induced motion for fluid structure interaction (FSI)
  • Evaluation of mixing performance enhancement by rotational mixing vane
  • Centrifugal force of swirl provides bubble detachment from cladding surface, with CHF enhancement and rotational motion reduces pressure drop
  • Enhancement of the safety margin and power uprate for PWR
