University of Twente researchers found injecting bubbles underneath a ship’s hull causes them to be pushed against the hull’s surface making an air bearing surface. In the surface layer between the ship and water, these air bubbles cause less friction: it’s also known as air lubrication. In practice, friction can be reduced 20 percent, with […]

Rice University scientists describe in great detail and more precisely how bubbles form, evolve and act and in turn how they could be used to extract more oil from already discovered fields. In a new study led by Rice chemical and biomolecular engineer Sibani Lisa Biswal associate professor of chemical and biomolecular engineering with lead […]
