Levitated droplet dye laser.
We present the first observation, to our knowledge, of lasing from a levitated, dye droplet. The levitated droplets are created by computer controlled pico-liter dispensing into one of the nodes of a standing ultrasonic wave (100 kHz), where the droplet is trapped. The free hanging droplet forms a high quality optical resonator. Our 750 nL lasing droplets consist of Rhodamine 6G dissolved in et...
متن کاملDynamic and Deformation of a liquid Droplet in a Convective Two-Dimensional Laminar Flow
The objective of this research is to develop an accurate numerical method to be used in showing the deformation of a liquid fuel droplet in a convective field. To simultaneously solve the internal liquid droplet flow field as well as the external gas phase flow field, a nonstaggered rectangular grid system without any coordinate transformation is used. Transition from the gas field to the liqui...
متن کاملNonaxisymmetric shapes of a magnetically levitated and spinning water droplet.
The shape of a weightless spinning liquid droplet is governed by the balance between the surface tension and centrifugal forces. The axisymmetric shape for slow rotation becomes unstable to a nonaxisymmetric distortion above a critical angular velocity, beyond which the droplet progresses through a series of 2-lobed shapes. Theory predicts the existence of a family of 3- and 4-lobed equilibrium...

متن کاملA numerical study of droplet deformation in a flat funnelform microchannel
Motivated by recent reported experiments, droplet deformation in a flat funnelform diverging microfluidic channel has been numerically studied. The structure of our microchannel is composed of two consecutive elements including a straight channel and a diverging channel. In this work, instead of solving the 3D Stokes equation, we solve a depth-averaged problem which is labeled two-dimensional p...
