ABSTRAKT

The 1D module of the CATHARE code has been used to perform calculations of two water hammer tests in which phase change is of great importance. Several sensitivity studies on the meshing, the time step, the flashing, and the condensation model constants have been performed for both tests. A model specific to wall elasticity has been added since it affects the speed of sound. All these works result in a good prediction of the pressure and void fraction fields until the occurrence of the largest pressure peak, which is the most important for pipe design.
