Although particle scavenging is investigated for many reasons, the focus of this work is on the removal of coal dust particles from mining environments. Currently, sprays play an important role in reducing the level of dust in coal mines, and also in other types of mines. However, the level of respirable dust in mines remains high and is difficult to control. We are working on method for changing the shape of drops in sprays so that they are more effective in removing particles. This removal of particles by drops is called 'scavenging' and is used in wet scrubbers.
This work is funded by a grant from the CDC through NIOSH. The current research focuses on the use of ultrasonics to manipulate the shape of water drops. The hope is that proper manipulation of drops via ultrasonics will improve the capability of sprays to remove particles.
Below is a photograph of an ultrasonic transducer which is used to levitate drops, allowing us to study their particle scavenging capabilities. At the top left of this page is a picture of a drop being levitated above one of these transducers.
The entire setup used for levitating drops is shown below:

We have also studied at the removal of particles by raindrops:
