  We report the first high-order eddy-resolving simulation of flow over a
marine propeller using a recently developed high-order sliding-mesh method.
This method employs the flux reconstruction framework and a new dynamic curved
mortar approach to handle the complex rotating geometries. For a wide range of
working conditions, it is validated to predict the loads very accurately
against experiments. The method's low-dissipation characteristic has allowed
the capturing of a broad spectrum of turbulence structures for very long
distances even on a very coarse grid. Comparison with a previous low-order
simulation is also carried out to show the low-dissipation advantage of the
present simulations. From detailed load analysis, the major loads and their
distributions and time and frequency scales are identified. Visualizations of
the instantaneous, phase-averaged, and time-averaged flow fields have revealed
the processes of tip vortex formation, major vortex evolutions, and flow
instability developments at different working conditions. The effects of
different fairwaters on the propeller's overall performance are also
quantitatively assessed.
