Hydraulic transient analysis for pump trip scenarios: what the models miss

MOC vs CFD for a pump-trip transient in a 12-km pipeline with two intermediate booster stations. The check valve slam event the 1D model predicted correctly but for entirely the wrong reason.

• Transient event reconstruction and pressure trace analysis
• 1D method-of-characteristics and 3D CFD model comparison
• Failure mode identification and root cause determination
• Surge suppression specification and system protection design
