There has been a lot of buzz lately on the internet regarding work at the Oak Ridge National Laboratory to develop a dryer that uses ultrasonics instead of heat to dry things. The major thrust seems to be to replace the conventional domestic clothes dryer (which uses heat to evaporate water) with one that uses ultrasonics …
The environment in the area of an industrial cleaning system is often not a “healthy” one for personnel or equipment. Caustic and acidic cleaning chemistries rise as mist above cleaning processes along with humidity and heat. Although our first thought is to protect personnel from these hazards, the equipment can also suffer serious consequences as a …
When a liquid or a gas flows uniformly and without turbulation, the result is called “laminar flow.” The most visual example of laminar flow for most of us are those arching water displays where perfectly shaped slugs of crystal clear water flys gracefully through the air from one point to another. When I first saw this effect at …
Maximum ultrasonic performance requires the most efficient transfer of ultrasonic vibrations from the ultrasonic transducers to the liquid in the process tank. This is generally accomplished by applying ultrasonic transducers directly to the exterior surfaces of a tank containing the process liquid. Transducer attachment techniques favor attachment to metals like stainless steel. What if the chemistry to be used …
