Deformation and dewetting of thin liquid films induced by moving gas jets

“…In the galvanization of steel, for example, so-called jet stripping is a common technique [1][2][3][4][5][6][7][8], where the thickness and uniformity of a metallic coating on a moving sheet of steel is adjusted by the pressure and shear stress of an impinging slot jet. The analogous effect is also relevant in smaller scale systems, such as ultrathin films of hard disk lubricant [9].…”

Normalizing study on the characteristic size of the stable cavity induced by a gas-jet penetrating into a liquid sheet

“…It is considered as a method of gas-jet wiping to control the final liquid film thickness in film, paper and wire coating manufactures [1,2] and utilized as a common decarburizing technique in oxygen steelmaking to reduce the carbon content in the metal bath [3][4][5]. In addition, it is entitled as a novel sealing way to prevent the liquid between the lens and wafer from leaking in immersion lithography [6,7].…”
