Distributed hydrodynamic forces on circular heave plates are investigated by large-eddy simulation (LES) with volume of fluid (VOF) method. First, the predicted added mass and drag coefficients for a whole heave plate is validated by published experimental data. The distributions of hydrodynamic loads on the circular heave plates are then investigated. It is found that maximum dynamic pressure occurs at the plate centre and decreases monotonically towards the outer regions. Finally, formulas of distributed added mass and drag coefficients in the radial direction are proposed based on present numerical simulations, and effects of aspect ratio and diameter ratio on the distributed added mass and drag coefficients are investigated.
