Effects of grid spacer with mixing vane on entrainments and depositions in two-phase annular flows
Nuclear Engineering and Technology, 2015 The effects of mixing vanes (MVs) attached to a grid spacer on the characteristics of air–water annular flows were experimentally investigated. To know the effects, a grid spacer with or without MV was inserted in a vertical circular pipe of 16-mm ...

Effect of Weld Properties on the Crush Strength of the PWR Spacer Grid [PDF]
Science and Technology of Nuclear Installations, 2012 Mechanical properties in a weld zone are different from those in the base material because of different microstructures. A spacer grid in PWR fuel is a structural component with an interconnected and welded array of slotted grid straps. Previous research

LINEAR INSTABILITY ANALYSIS OF A WATER SHEET TRAILING FROM A WET SPACER GRID IN A ROD BUNDLE
Nuclear Engineering and Technology, 2013 The reflood test data from the rod bundle heat transfer (RBHT) test facility showed that the grids in the upper portion of the rod bundle could become wet well before the arrival of the quench front and that the sizes of liquid droplets downstream of a ...

Using a desktop grid to support simulation modelling [PDF]
, 2006 Simulation is characterized by the need to run multiple sets of computationally intensive experiments. We argue that Grid computing can reduce the overall execution time of such experiments by tapping into the typically underutilized network of ...
