Shape of Slender Axisymmetric Ventilated Supercavities

Figure 19

The dependences 𝜎^(cr)₀ (𝜎_𝑣) for the isothermal cavity (𝛾=1) on the neutral shaped hull (81) at Fr→∞ and 𝜀=0.1. Curves 1–4 correspond to 𝛽=0.1 and curves 5–8 correspond to 𝛽=−0.1. Solid lines 1–3 and 5–7 correspond to the values 𝐿_𝑏/𝐿₀=0.5, 0.7, and 0.9, respectively. For comparison the cases of the empty cavity are shown by dashed lines 4 and 8. The restriction 𝜎^(cr)₀=𝜎_𝑣 is shown by the bold line 9.
