Longitudinal Sloshing Behaviors of Horizontal Cylindrical Liquid Tanks Subjected to Harmonic and Seismic Excitations [PDF]

Journal of Applied Fluid Mechanics
In the present study, the sloshing behavior of horizontal cylindrical liquid tanks under longitudinal excitation is investigated numerically. Shallow liquid wave theory has been used to derive the equations governing fluid motion. In the numerical model,

Novel Characteristics of Valveless Pumping [PDF]

, 2009
This study investigates the occurrence of valveless pumping in a fluidfilled system consisting of two open tanks connected by an elastic tube. We show that directional flow can be achieved by introducing a periodic pinching applied at an asymmetrical ...

Numerical simulation of wave generation in a tank by wall and floor oscillation [PDF]

مهندسی عمران شریف, 2021
Tsunamis occur every year in different seas and oceans around the world. These waves propagate at high speeds in various directions and, if they reach the shore, cause irreparable damage to these areas and their structures and facilities.

The Effect of Porous Media on Wave-Induced Sloshing in a Floating Tank

Applied Sciences, 2022
Placing porous media in a water tank can change the dynamic characteristics of the sloshing fluid. Its extra damping effect can mitigate sloshing and, thereby, protect the integrity of a liquefied natural gas tank.
