Measuring tsunami forces to design safe cooling systems for (nuclear) power plants
Published: 20 November 2017
Numerical models, such as the free, open source CFD software OpenFOAM, are often used to design such intake structures. However, these tools can only provide reliable results, when they are calibrated against accurate measurements. For this purpose, physical scale model tests were performed at Deltares, where forces on an intake structure were measured during a tsunami event (see video). Additionally, the flow patterns around these structures were measured by means of highly detailed PIV measurements. These advanced measurements allow us to get a thorough insight into the flow patterns near the intake structure in case of a tsunami event. Based on this fundamental understanding in hydraulic behavior near the intake structure, we will able to better predict the hydraulic loads that occur during a tsunami event.
These tests have been performed in the Deltares’ Eastern Scheldt flume test facility. These tests will be used as validation material for our numerical models, which can be used as a design tool.
