| The ⑥–⑦ is same as the boundary-domain flow of r eD [Ω] & r eD [Θ] | ||||
| ④Weak CpBF: const slope | ④Strong CpBF: const slope | |||
| ⑤Weak pseudo-CpBF: const slope m | ⑤Strong pseudo-CpBF: const slope m | |||

| ⑦Weak CpBF: const pressure L | ⑦Strong CpBF: const pressure L | |||
Notes: “CBF” is Closed Boundary Flow, “IARF” is the Infinite-Acting Radial Flow, and “CpBF” is the Constant-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.
