MOC-CFD Coupled Approach for the Analysis of the Fluid Dynamic Interaction between Water Hammer and Pump
Publication: Journal of Hydraulic Engineering
Volume 141, Issue 6
Abstract
A one-dimensional (1D) system and three-dimensional (3D) component cosimulation method based on the method of characteristic (MOC) and computational fluid dynamics (CFD) was proposed to study the interaction between valve-induced water hammer and pump during the rapid closing of the valve. In a long pipeline system, the pump was treated as a 3D CFD model using Fluent code, whereas the remaining system models (e.g., pipe, valve) were represented by 1D components using MOC. The numerical coupling and integration of both models were realized by a coupled code written using Visual Basic. The coupling theory and procedure were described in detail. MOC-CFD steady coupling in the case of the fully open state of the valve was first conducted. The corresponding results showed that the steady cosimulation can accurately determine the operating conditions. A transient cosimulation for the rapid closing procedure of the valve was conducted to study the interaction. The relative dynamic behavior obtained by MOC-CFD cosimulation was compared with that using MOC calculation alone. Transient simulation demonstrated that MOC-CFD coupling analysis was closer to real conditions because of considering the effect of fluid inertia. The effect was further explained through a comparison of internal and external characteristics between the transient and quasi-steady assumptions.
