Damping of liquid sloshing by foams: from everyday observations to liquid transport
- 331 Downloads
When a container is set in motion, the free surface of the liquid starts to slosh, i.e. oscillate. For a frequency of motion corresponding to the resonant frequency of the surface wave, the amplitude of the waves can increase significantly and if the amplitude of sloshing is large enough splashing and/or drop formation are possible (Ibrahim 2005; Faltinsen and Timokha 2009). The sloshing dynamics lead to challenging technical constraints in various applications. For example, sloshing leads to considerable pressure forces on the walls of the containers used for transport of oil and liquefied gas (Kim et al. 2007). Therefore, the characterization of the amplitude of the generated waves and the investigation of methods to damp sloshing such as solid foams (Chun et al. 2014) or baffles (Liu and Lin 2009) are important.
