Abstract. An in-house Navier-Stokes multiphase VOF (Volume-Of-Fluid) solver is used to study sloshing phenomena in a partially filled rectangular tank subjected vertical sinusoidal excitation. The flow dynamics found be significantly affected by acceleration and forcing frequency. Specifically, when the strong excitation frequency low, exhibits more chaotic three-dimensional nature. Consequentl...

We report an experimental study of the three-dimensional spatial structure of the low-frequency temperature oscillations in a cylindrical Rayleigh-Bénard convection cell. Through simultaneous multipoint temperature measurements it is found that, contrary to the popular scenario, thermal plumes are emitted neither periodically nor alternately, but randomly and continuously, from the top and bott...

This paper deals with the experimental studies of sloshing of liquid in partially filled container subjected to external excitation. An experimental set-up is designed to study the behavior of liquid sloshing in partially filled prismatic container. At every instant of time, slosh amplitude is computed at specified location with the help of capacitance probe. The resulting slosh heights for var...

The possibility of employing internal wall as mass absorber in rectangular water storage tanks subjected to harmonic ground motion excitation is investigated in this paper. Internal walls are used in these tanks usually for service performance purposes, which could be used as mass absorber to control seismic demand on tank's exterior walls. Derivation of the response of the coupled system inclu...

Liquid sloshing in ship tanks would have a direct effect on dynamic stability, and thus is of great importance for navigation safety. To calculate the sloshing-induced force real tanks, this paper presents an approach to numerically simulate liquid-sloshing complex using moving particle semi-implicit (MPS) method. The calculated used investigate different excitation conditions which realistic m...

Cylindrical steel tanks are important components of many industrial plants such as oil refineries and chemical plants. Usually failure of cylindrical tanks leads to serious consequences. During the past earthquakes such as 1964 Alaska and 1999 Turkey seismic performance of cylindrical tanks revealed that tanks are seismically vulnerable. Therefore, evaluation of seismic performance of these str...

Numerical simulations for free surface flow models, which are water entry of several rigid bodies, fluid tank sloshing and flood disaster over several rigid bodies were conducted by using an Incompressible smoothed particle hydrodynamics (ISPH) method. The governing equations are discretized and solved with respect to Lagrangian moving particles filled within the mesh-free computational domain ...
