Abstract
The simulation of the MYRRHA free-surface water experiment using an Arbitrary Eulerian-Lagrangian Moving Mesh Algorithm implemented in the Star-CD commercial CFD code is presented.
In spite of the complexity of the surface morphology, relatively to this type of approach for free surfaces modelling, results show that the algorithm is able to give quantitatively correct results in terms of velocity profiles. Although no measurements of the surface shape are available, it can be guessed that it is well predicted.
Better results are obtained without taking into account surface tension, whose effects seem to be overestimated, probably due to the presence of surface discontinuities in the real free surface.
