Advanced numerical modelling of the hydraulic functions of the intake system
DHI applied the CFD methodology for the 3D simulation of the wave transformation and penetration from offshore into the intake basin and the induced flow towards the pumps. The study was conducted on both the existing and the upgraded design. The model offered the flexibility of recording water level variations and velocities throughout the system, which allowed us to calculate the residual wave agitation in the suction chamber and to assess the flow distribution towards the pumps. The CFD model thus assisted CRC in testing the current design of the intake system during harsh wave conditions offshore and in predicting the response of the upgraded design, with particular focus on the improvement of flow distribution to the pumps.
DHI has been using advanced and accurate numerical tools in similar projects in the past 20 years, in combination with physical model tests that we perform in our own dedicated facilities.
