Induced Particle Sloshing in a Rotating Container
نویسندگان
چکیده
Vibration absorbers are employed for both structural safety and comfort reasons. This paper explores a novel absorber which uses the sloshing of granular particles to dissipate energy in a rolling container. Some of the parameters which affect energy dissipation have been experimentally studied. Detailed description of one experiment is given. Further work involves numerical exploration.

Self-Induced Rotary Sloshing Caused by an Upward Off-Centered Jet in a Cylindrical Container
Self-induced rotary sloshing caused by an upward off-centered jet in a cylindrical container is numerically and experimentally investigated. Unlike the regular jet-induced rotary sloshing, the present off-centered case could contain components of higher fluctuation in the surface wave and the amplitude exhibits different values in various view angles. A simple geometrical model for the amplitud...
متن کاملاستفاده از روش SPH برای مدلسازی Sloshing در یک مخزن نیمه پر
The motion of fluids within partially filled containers has been the subject of much study by scientists and engineers due, in large part, to its importance in many practical applications. For example, civil engineers and seismologists have actively studied the effects of earthquake-induced fluid motions on oil tanks and water towers. In recent years, aerospace engineers have been concerned wit...
متن کاملCoupled sloshing in hyperbolic containers suspended as a bifilar pendulum
The coupled interaction between a sloshing fluid in a partially-filled container suspended as a bifilar pendulum is investigated. The sloshing fluid has a free-surface upon which waves are generated this fluid contributes a restoring force to the container motion by its weight through the wire suspensions and the free-surface waves may either enhance or diminish the restoring force through hydr...
متن کاملTransfer Control and Curved Path Design for Cylindrical Liquid Container
A spherical pendulum-type model was constructed to represent liquid sloshing in a cylindrical container caused by container transfer along a curved path. The model was used to design a curved path and a transfer control system in consideration of the damping of sloshing in the container. The curvature radius of the curved path and the acceleration of the container were determined using an input...
متن کاملDamping of liquid sloshing by foams: from everyday observations to liquid transport
We perform experiments on the sloshing dynamics of liquids in a rectangular container submitted to an impulse. We show that when foam is placed on top of the liquid the oscillations of the free interface are significantly damped. The ability to reduce sloshing and associated splashing could find applications in numerous industrial processes involving liquid transport. When a container is set in...
