WebThe flow coefficient ϕ is a measure of the angle of incidence of the flow and the aerodynamic forces developed are critically dependent upon this parameter. Typical results based on predictions and experiments of the non-dimensional pressure drop p * = Δ p / ( ρ ω 2 D t 2 ) and efficiency are shown in Figure 9.26 . WebMar 5, 2024 · Maximum Turning Angle. (12.4.1) ν ∞ = π 2 [ k + 1 k − 1 − 1] The maximum of the deflection point and the maximum turning point are only a function of the specific heat ratios. However, the maximum turning angle is much larger than the maximum deflection point because the process is isentropic.
