Introduction
- Advice on SX connections & number of cells to connect to 2D domain – implications
- Flow regimes – theory behind each.
- How to check for the flow regime – link to check file
- How do we sub divide logic rules (operational culverts)*
- Losses – fixed, Englehund, automatic manholes etc.
- Provide some justification on the ‘default’ height/width, entry/exit losses.
Flow Regimes
Regime | Description |
---|---|
Unsubmerged entrance and exit. Critical flow at entrance. Upstream controlled with the flow control at the inlet. | |
B | Submerged entrance and unsubmerged exit. Orifice flow at entrance. Upstream controlled with the flow control at the inlet. |
C | Unsubmerged entrance and exit. Critical flow at exit. Upstream controlled with the flow control at the culvert outlet. |
D | Unsubmerged entrance and exit. Sub-critical flow at exit. Downstream controlled. |
E | Submerged entrance and unsubmerged exit. Full pipe flow. Upstream controlled with the flow control at the culvert outlet. |
F | Submerged entrance and exit. Full pipe flow. Downstream controlled. |
G | No flow. Dry or flap-gate active. |
H | Submerged entrance and unsubmerged exit. Adverse slope. Downstream controlled. |
J | Unsubmerged entrance and exit. Adverse slope. Downstream controlled. |
K | Unsubmerged entrance and submerged exit. Critical flow at entrance. Upstream controlled with the flow control at the inlet. Hydraulic jump along culvert |
L | Submerged entrance and exit. Orifice flow at entrance. Upstream controlled with the flow control at the inlet. Hydraulic jump along culvert. |
