Numerical Investigation of Water Entry of Half Hydrophilic and Half Hydrophobic Spheres

Figure 16

Water entry of half-half spheres with different mass ratio , respectively. The three cases have the same impact speed U₀ = 2.37 m/s and the same half-half surface condition = 120°/60°. The time when the sphere impacts on the free water surface is defined as t = 0 ms.
