摘要:

Sloshing is a common phenomenon in nature and industry, and it is important in many fields, such as marine engineering and aerospace engineering. To reduce the sloshing load on the side walls, the topology optimization and optimal control methods are used to design the shape of the board, which is fixed in the middle of the tank. The results show that the new board shape, which is designed via topology optimization, can significantly reduce the sloshing load on the side wall.

关键词: finite elements, subsonic flow, supersonic flow, sloshing, topology optimization, volume of fluid (VOF) method, suppressing sloshing
