Semi-analytic approach for treating fixed and mobile boundaries: validation cases

This paper shows some validation cases of the improved SPHERA code for treatment of 3D irregular boundaries, both fixed and mobile, by means of the semi analytic approach. In the first case the jet originated by the collapse of a water column impacts on a rigid fixed box at the bottom of a tank. In the second case the simulation of a wave generator in a 3D experimental tank has been carried out. Finally, in the third case a transient wave has been simulated in the condition of the benchmark “Tsunami Wave Attack on Beach” based on the experiment realized at the Oregon State University. The semi analytic technique has been successfully applied in all the cases, and the results show a satisfactory degree of accuracy. The simulation of the effects of moveable structure allows to extend the field of application of the SPHERA code to several hydraulics problems having strong environmental impact.
