Shape of Slender Axisymmetric Ventilated Supercavities

Figure 8

The cavity shapes (27) at zero ventilation rate on a conic-cylindrical hull (𝑥₁=5, 𝑥₂=8, 𝑅_𝑏0=𝑅_𝑏1=0.5, 𝑅_𝑏2=2.5, 𝜀=0.1, and Fr→∞) for 𝛽=0.1 (curves 1–4, the corresponding values of 𝜎₀ are −0.2626, −0.046, 0, and 0.1, resp.), for 𝛽=0, 𝜎₀=0 (curve 5), and for 𝛽=−0.1 (curves 6–9, the corresponding values of 𝜎₀ are −0.2, −0.046, 0, and 0.2, resp.). The cavity shapes corresponding to the zero cavitation number (curves 3, 5, and 8) are shown by dashed lines.
