The treatment of large tumors such as sarcomas with intra-operative radiotherapy using a Mobetron is often complicated because of the limited field size of the primary collimator and the available applicators (max Ø100 mm). To circumvent this limitation a prototype rectangular applicator of 80 x 150 mm(2) was designed and built featuring an additional scattering foil located at the top of the a...

Placing porous media in a water tank can change the dynamic characteristics of sloshing fluid. Its extra damping effect mitigate and, thereby, protect integrity liquefied natural gas tank. In addition, out-of-phase force enables to serve as vibration absorber for floating structures ocean environment. The influence on wave-induced fluid and associated interaction with substructure ambient wave ...

In this study, the two-dimensional sloshing of water in a stepped based tank partially filled was analyzed using an arbitrary Lagrangian–Eulerian adaptive fixed-mesh method and including Smagorinsky turbulence model. The numerical model is verified by contrasting predictions made with experimental results. subjected to controlled one-directional motion imposed shake table. free surface evolutio...
