We analyze theoretically a high-speed drainage of liquid films squeezed between a hydrophilic sphere and a textured super-hydrophobic plane, that contains trapped gas bubbles. A superhydrophobic wall ...
Air Drag Force on a Yarn and Use of a Coaxial Jet for Yarn Operation
Yarn operation Air drag force Coaxial circular jet Coaxial annular jet Power-saving
