New...
Two different configurations of a phase Doppler instrument have been used to measure drop size and two components of velocity directly above the film as well as the size and two components of velocity of the air bubbles inside the deep pool....
By measuring the jet droplet compositions, our study directly evidences marine oily aerosol formation by bubble bursting jets with oil slicks, and may also serve as a valuable step to further consider the role of physicochemistry in the hydrodynamic phenomena related to bubbles. Meanwhile, although ...
An underwater optical link is proposed for communication between sensors on a swimmer during training.Tests in still-pool water, still-spa water, and bubbles-spa water demonstrated the attenuation of the signal. The system uses a light emitting device (LED) (520 nm) and optical detector and ...
Small air bubbles provide soothing massage while 360° air inlets ensure a whole-body experience in our Jacuzzi® heated jetted bathtubs. The heated air blower keeps water pleasurably warm for a bathing experience like none other. Featured Pure Air® Bathtubs Linea® Drop In Bath ...
We elaborate the retraction mechanism of the entrapped air film in terms of liquid viscosity. We found the criterion for deciding if the entrapped air evolves into single or double bubbles, as determined by competition among inertia, capillarity, and viscosity. Low viscosity and low surface tension...
When a plunging jet impinges into a pool of liquid, air bubble entrainment takes place if the inflow velocity exceeds a threshold velocity. This study investigates air entrainment and bubble dispersion in the developing flow region of vertical circular plunging jets. Three scale models were used ...
