AbstractWe present large-eddy simulations of flow and heat transfer in a wire-wrapped fuel assembly at subchannel Reynolds numbers of Reh=4684-29184. The domain consists of a single pin in a hexagonally periodic array, corresponding to two interior subchannels. Periodic boundary conditions are also used in the axial direction over a single wire-wrap period.
