A new moving staggered mesh discretization for the numerical simulation of incompressible flow problems involving free-surfaces is presented. The method uses the staggered mesh to obtain speed and conservation properties. Mesh motion provides a high quality mesh in the interior and detailed resolution of the free-surface motion on the surface. Mesh flipping allows for optimal mesh connectivity ...

The analysis of violent sloshing is great interest for European aeroplane manufacturers. It has been widely reported that aircraft fuel significantly damps wing vibrations, but the complexity fluid–structure phenomena still demands further research. aim this work to define an experimental methodology quantify force acting on a vertical Single Degree Of Freedom (SDOF) tank when accelerations are...

The effect of the sloshing motion liquid in a tank on vertical transient single degree freedom system is investigated. Step release tests vertically vibrating structure, including containing liquid, demonstrate that added damping from depends upon amount fluid and maximum acceleration. was observed at 50% fill level showed three distinct response regimes during decay, all related to different m...

Surface tension tanks exploit the liquid surface in transport and gas–liquid separation to provide gas-free propellant for thruster. High efficiency of deflectors can ensure relocation microgravity environment within a short period time, which is helpful providing propellant. This paper explores through drop tower experiments numerical simulations with volume fluid method. The experimental resu...

In the past several years, continuous effort has been made in RIAM, Kyushu University to develop an efficient Cartesian grid method for violent free surface problems in ship and ocean engineering. Our researches have been focused on (1) Accurate and robust flow solver for multi-phase flows with solid bodies. (2) Conservative and smearingless interface capturing scheme. In the numerical method, ...

an elliptical tank cross-section is formulated to explore and optimization method, based on a real-coded genetic algorithm to enhance the roll stability limit of a tank vehicle. a shape genetic algorithm optimization problem is applied to minimize the overturning moment imposed on the vehicle due to c.g. height of the liquid load, and lateral acceleration and cargo load shift . the minimization...
