Boundary flow characteristics of Figure 4.
|Symbol description||Closed & const-pressure, r
[Ω] = r
|κ[Θ] > κ[Ω]||κ[Ω] > κ[Θ]|
|Response behavior||④Strong CBF: unit slope||④Strong CpBF: const slope (−2.5 is its limit)|
|⑤Weak CpBF: const pressure L = L 0/κ[Ω]||⑤Weak CBF: unit slope|
|⑥Strong CpBF: const pressure L = L 0/κ[Ω]|
Where κ[Ω] is the permeability ratio of const-pressure layer, L 0 is the pressure value when the κ[Ω] = 1.
Notes: “CBF” is Closed Boundary Flow and “CpBF” is the Const-Pressure Boundary Flow. “Strong” indicates the boundary layer is the main-flow layer, and “Weak” indicates the boundary layer is the non-main-flow layer.
