Nonlinear interactions among incident wave, tank-sloshing and freely floating body coupled motion are investigated. The fully nonlinear sloshing and body-surface nonlinear free surface hydrodynamics is simulated using a non-uniform rational B-spline higher-order panel method (NURBS) in time domain based on the potential theory. A robust and stable improved iterative procedure, iterative semi-im...

The performance of a two stage control design scheme on the control of liquid outpouring and the suppression of liquid sloshing during the outpouring phase of the pouring process is studied for the case of liquid containers carried by manipulators. The designed scheme, that does not require measurements of the liquid’s motion within the tank, combines a partial inverse dynamics controller with ...

We propose a control design scheme that aims to prevent undesirable liquid outpouring and suppress sloshing during the forward and backward tilting phases of the pouring process, for the case of liquid containers carried by manipulators. The proposed scheme combines a partial inverse dynamics controller with a PID controller, tuned with the use of a “metaheuristic” search algorithm. The “metahe...

Computational Fluid Dynamics (CFD) is a mathematical tool capable of simulating a wide range of fluid flows. Integrated CFD software has been applied to study the flows in oilfield separators. The influence of inlets, internals, and outlets has been studied with CFD simulations. Of particular value has been the ability of CFD to simulate wave induced sloshing in vessels mounted on floating plat...

Liquid sloshing is a common industrial problem affecting not only the dynamics of flow inside the container, but also of the downstream systems being fed from the container. This paper deals with the application of Computational Fluid Dynamics (CFD) for analyzing the possible effect of oil sloshing in compressors used in underground rail application on the continuous supply of lubricant to the ...

Many studies have been reported for the sloshing analysis in liquid containers. One of the major concerns in the marine hydrodynamic field is the accurate prediction of impulsive load on internal structures. During violent sloshing, the sloshing-induced impact load can cause a critical damage on tank structure. Such damage cases have been reported for oil tankers, LNG carriers and bulk carriers...

tuned liquid dampers (tld) are among passive control devices that have been used to suppress the vibration of structures in recent years. these structures must be adequately presentable as an equivalent single degree of freedom system with long fundamental period. the tld, located at the top floors of the structure, can dissipate the external input energy into the system through the sloshing ef...
