We present the results of an experimental investigation of the acoustics and fluid dynamics of Tibetan singing bowls. Their acoustic behaviour is rationalized in terms of the related dynamics of standing bells and wine glasses. Striking or rubbing a fluid-filled bowl excites wall vibrations, and concomitant waves at the fluid surface. Acoustic excitation of the bowl’s natural vibrational modes allows for a controlled study in which the evolution of the surface waves with increasing forcing… Expand
RESONANCE FREQUENCY VARIATIONS OF METALLIC TIBETAN SINGING BOWL WITH TEMPERATURE
Metallic signing bowls are used in sound therapy and in Buddhist prayers are widely studied for their resonance frequency modes [13,2]. Studies have also been carried out to understand the resonanceExpand
An Electro-Acoustic Implementation of Tibetan Bowls: Acoustics and Perception
Tibetan singing bowls are employed worldwide for meditation, music, relaxation, personal wellbeing, and religious practices. Each Tibetan bowl can produce a limited number of sounds, defined by theExpand
Digital Synthesis of Sound Generated by Tibetan Bowls and Bells
TLDR
A general algorithm was developed to synthesise the sounds of selected musical instruments with an axisymmetrical shape and impact excitation which resulted in a sound pressure signal in selected points in space surrounding the instrument which is consistent with the signal generated by the actual instruments, and the results obtained can improve them.

Self-organized oscillations of Leidenfrost drops
In the Leidenfrost effect, a thin layer of evaporated vapour forms between a liquid and a hot solid. The complex interactions between the solid, liquid and vapour phases can lead to rich dynamicsExpand
Nonlinear low-frequency gravity waves in a water-filled cylindrical vessel subjected to high-frequency excitations
In the experiments of a water storage cylindrical shell, excited by a horizontal external force of sufficient large amplitude and high frequency, it has been observed that gravity water waves of lowExpand
Comprehensive vibrational dynamics of half-open fluid-filled shells
TLDR
This study derives a theoretical framework encompassing elastic shell deformation with structural and viscous dissipation, accommodating arbitrary axisymmetric shell geometries and fluid levels; reductions to closed-form solutions under specific assumptions are shown to be possible. Expand
Self-oscillation
Physicists are very familiar with forced and parametric resonance, but usually not with selfoscillation, a property of certain dynamical systems that gives rise to a great variety of vibrations, bothExpand
Acoustic emission monitoring from a lab scale high shear granulator--a novel approach.
TLDR
Results from the discrete element model indicate that when larger particles are used the number of collisions the particles experience reduces, therefore larger particles results in less particles, which explains why the frequency content of the acoustic emissions reduces during granule growth.

Experimental investigations on the nonequilibrium dynamics of pattern formation in fluid and granular systems
Patterns are quotidian in nature. Distinct multiscale patterns are generally a consequence of nonequilibrium dynamical processes associated with mechanical or hydrodynamic instabilities. In thisExpand
Effects of microfluid in the veins of the deployable hindwings of the Asian ladybeetle on flight performance
TLDR
The effects of microfluid (hemolymph) in the veins of beetle deployable hindwings are investigated and will be helpful in designing new biomimetic deployable MAVs. Expand

Dynamics of a bouncing droplet onto a vertically vibrated interface.
TLDR
The bouncing droplet has been modeled by considering the deformation of the droplet and the lubrication force exerted by the air layer between theDroplets and the bath and found to be in good agreement with measurements. Expand
From bouncing to floating: noncoalescence of drops on a fluid bath.
TLDR
An analysis using lubrication theory accounts for most of the observations, showing that a steady regime where a drop can be kept bouncing for any length of time is found. Expand
