Variable frequency drives (VFDs), also known as variable speed drives (VSDs), are used to modulate the speed of motors in various applications, from hydronic water pumping to VAV fan units to vacuum ...

Engineers have found a way to eliminate the fluid flow 'dead zones' that plague the types of electrodes used for battery-based seawater desalination. The new technique uses a physics-based tapered ...

Researchers investigated the propulsion mechanism by visualizing water flow around a swimmer during underwater dolphin-kick swimming in a water channel via particle image velocimetry. Their findings ...
