Numerical Modeling of Unsteady Cavitating Flows around a Stationary Hydrofoil

Figure 3

Comparisons of the measured versus predicted pressure coefficients obtained using different time step sizes, Δ𝑡. The lines represent the mean values and the error bars represent the level of fluctuations. 𝜎=1.49, Re = 750,000, 𝑉_∝=5 m/s, and 𝛼=6^∘. Merkle cavitation model, 𝑛=3.
