Response behavior | The ④–⑤ is same as the boundary-domain flow of r eD [Ω] & r eD [∞] | |||
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 | |||
⑥Strong CBF: unit slope | ⑥Weak CBF: unit slope | |||
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.
