Numerical Simulations of Air Cavities in Inclined Plunging Jets

Figure 15

Nonlinear regression: (a) simulated versus estimated values of L₂/D (the unit of θ₀ is “°” and the unit of V_in is “m/s”); and (b) graphical error analysis presenting relative errors (δ) versus frequency of errors in predictions of L₂/D [(δ = |simulated − estimated|/observed × 100%].
