elevated tanks are important structures in storing vital products, such as petroleum products for cities and industrial facilities, as well as water storage. these structures have various types and are constructed in a way that a greater portion of their weight is concentrated at an elevation much about the base. damage to these structures during strong ground motions may lead to fire or other ...

A spectral/hp element code, incorporating a velocity-pressure formulation, is used to simulate free surface flows. Non-linear pressure and velocity boundary conditions are applied on the moving free surface, the tracking of which is facilitated by the implementation of an Arbitrary Lagrangian Eulerian (ALE) formulation. The derived algorithm is validated by comparing the numerical results evalu...

Elevated tanks are very important structures and consist of various types. Water supply is vital to control fires during earthquakes. Also they are utilized to store different products, like petroleum supplies in cities and industrial zones. Damage to these structures during strong ground motions may lead to fire or other hazardous events. Elevated tanks should stay functional after and before ...

This paper describes a novel numerical model aiming at solving moving-boundary problems such as free-surface flows or fluid-structure interaction. This model uses a moving-grid technique to solve the Navier–Stokes equations expressed in the arbitrary Lagrangian-Eulerian kinematics. The discretization in space is based on the spectral element method. The coupling of the fluid equations and the m...

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 ...

One of the main vibration problems of aerospace vehicles with liquid fuel propulsion system is fuel sloshing. This phenomenon is a low frequency vibrational challenge which can affect the motion of the vehicle and degrade the stability of the main control system. In this regards, the motion of the liquid will be very critical when the frequency of the sloshing is very close to the frequencies o...

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...

TLD is a tank filled with water and serves as a dynamic vibration absorber for passive control of structures. This paper addresses the comparisons of TLD performances corresponding to different tank geometries including rectangular and conical shapes. Due to the importance of water and tank weight as a load on top of a building, volume is considered to be a constant parameter in this study. Fir...
